Haha. OK, I'm not guilty of that one! I retired the aggressive techniques except for the "two plier twist mode", rumoured to have been used on a FIVE FIGURE coin by somebody... If I needed the date, I just don't think I could come up with a bid for that one. Good Luck to the seller!

You guys have already seen the London Coins Auction Lot 1985 (I think!) which is an "EF" 1905 2/6. Wow, just too much edge business going on and some less than strategic hits on obverse, etc.

Yes, I still like CC, though the firm has changed a bit & have gotten some very nice bits through NP. Ras, as you like to call him, has the most interesting lists that are like treasure hunts - a lot of stuff very high but some great bits hidden in there. Have even bought some fairly cheap stuff that was really good and a couple of farm-ransoming bits as well. Funny, don't seem to recall ever dealing with Mitchell but will keep my eyes and ears open. Back to the original coin, I like to see how these perform in auction but best to be there live or over the 'net to follow interests and the pacing of it. So just how an '05 do in a competitive auction? Unc, EF coins...

I think he's run into the problem that small/medium size dealers now have: no stock. Not an excuse, but rather a guess.

Colin, you got us all behaving like sharks with blood in the water. OK, I am guilty too. Will you be selling through one of the major auction houses. Guess I might bump heads a bit with Accumulator as I do love pennies and not just the silver - but get just a tad loonier over silver Vicky bits.... A coin I recently got perhaps as rare as unc '05 2/6 is the MS66 1889 sm Hd shilling. NIIIIIICCCCCCEEEEEE!

My likely unpopular view is the coin in question is more likely an EF obverse, GEF reverse with some signs, IMO, Also think its been cleaned a bit... Still nice. My value, if anyone cares is probably closer to 4k mark.

The off year proofs and patterns would I think tend to be a stopper, let alone the E8 issues and coins such as the 1954 penny...

I also seem to recall Spink having a Mint State specimen in about 1980 that was pictured in at least one of their SNCs (the good ole days)..

Have that catalogue somewhere, able to post a picture? I seem to recall a posting on these boards about these before. I am not convinced there definately was only one die combination as the extant population is either too worn, and/or decent specimens far too few to make such a pronouncement IMO.

And complete collection! Wonderful! Well, most of the rest of us can only hope one day. I fear that the endpoint changes along our collecting paths, never quite gettiing there....

Ouch! Why do almost all the '82 London pennies look as though they've been lying at the bottom of some creek for 100+ years?

Well here is one I have used more recently than I care to tell: two pliers, one on either side and twist it. I DO NOT RECOMMEND THIS!!!!! What happens is at some point the torsional rigidity is overcome and the slab comes apart in shards which fly all over the place - it is satisfying too! Naughty...

Colin, funny but sad story. I have a similar one, and not to pirate this thread but will note that I had a matte proof 1951 crown in a slab and HIT IT WITH A HAMMER to break it out. Well, the first blow didn't do it so I hit it again and HIT the rim of the crown and DENTED it (fortunately not badly)....

Yes, guilty - it seems people just get confused so feed them the redundancy..I've been meaning to get the halfpenny but just don't get excited for what is an 8-10k pound proposition for the coin. Even though more common I really like the full penny size and think the best specimens have a long way to go upward at "only" 6k pounds for a superior specimen such as the one just sold or the Colin Adams specimen. I sold away a superior 1903 halfcrown about 4-5 years ago to get one of the 1860 farthings (plus about 16 other silver bits)...

Wow, that seems a rather nice price you got there!

Yes, I think a good point about the counterfeits of the '05s. Is your gold farthing of the old larger copper modulus?

That would be the copper large modulus halfpenny. US market = HUGE, and therefore demand higher for such rarities. A US coin of equal rarity even in an unpopular series would have to go 1+million USD. Australia = "managed demand increase" . A more complicated situation but note there are mechanisms whereby a numismatic issue can be purchased with retirement funds. Now there is no doubt more to it than just that but that is just a portion of it. I can see the '05 2/6 going for 15-20 k or even higher before so very long with the '03 not far behind at maybe 70%.

I think I would take exception to the 1905 half crown NOT being rare in Unc. This coin is in fact prohibitively rare, but the change in relative values to other E7 2/6 IMO is more a function of demand flux in the 21st Century. Condition and rarity absolutely are the major driving forces to big prices, and this coin would fit the bill (theoretical as CC's is a bit less). I have seen one in PCGS63 that was slabbed some 6 or 8 years ago and definately fit the bill and would hit the 10k mark. Perhaps one other, and Rob would correct my memory but I believe that Colin Adams even had difficulty with these dates ('03 & '05)... What would be the value for the less loved, but still admired 1903 2/6 in a like state? 7k? Also IMO the two half crowns may have decent potential for further gain yet in value as they are quite rare...

Well, no chance for me to go either, but as much as I like Baldwin's and their material I too agree that prices have blown up. Did you see on their list the price for the set of five pattern E2 florins? Ouch!!

Ah yes, silver-coloured not silver as these are plated bits - a wash of copper or so on the steel for later dated copper coins...

I quite agree with Argentum's points. It seems coins have different prices depending on the venue, and that on occasion bidding frenzies can "blow up" the price - either at a traditional auction or an ebay one.

Acetone - no damage just colour change usu. very subtle. I am an absolute fan of acetone esp. on silver (can you imagine?)... I have no experience with EDTA although ChKy's example shows a bit of redness - I think I see it - so perhaps a danger to otherwise mint red coins with good lustre. Vinegar is a much stronger acid source in my experience, so be careful as it doesn't just work on the desired verd. spot... Rob, I think I am seeing that effect but have seen it even stronger. There is supposedly some solvent that takes care of the blueness as well??? FYI: The book, maybe obtainable from Amazon or the like is: Weimar W. White "Coin Chemistry Including Preservation and Cleaning"

Uhhh, Peck I think my Organic chem Prof would have been horrified at that explanation. And since its been 35 years I've forgotten some of the "bits and pieces". However, I do remember polar and non-polar & hydrophilic/-phobic, etc. Olive oil is a complex mixture of substances with most of them being hydrophobic (archaeic terminology to be sure), lipophilic substance properties that even with shifts in polarity tendency such as with the oleic acid would not be so readily miscible in water & not particularly that the acid would not be "friendly" to other acids (i.e. vinegar).... OK, sorry for some sorry pseudo-science.... Anyway, IMO, I would not like to keep a mint red penny of lated milled vintage to bathe in olive oil for any long period of time... In a related vein, I recall reading somewhere about changes in acetone and its degradation after longer exposure to copper surfaces. As far as it goes I believe I have seen some slight colour changes with copper exposure to acetone for even shorter periods. I am quite leery of some of those substances occasionally available such as "Blue Ribbon" or the more worrisome "MS70". One of them causes copper to turn blue and I have seen one of the 1860 proof copper farthings with this bluish lustre! Yikes!!

How do those kids say it (with regards to CGS) - NOT! I was visiting about 2 or three years ago to the NYINC show when I pointed out to the CGS folks that the 1875 farthing in their FEATURED display case actually was an 1875 H!

Wow, not sure if I like the responses. Olive oil is acidic, and can not say if this property deteriorates with time but know that it will continue to react with coin surface - I have had some strip to an unnatural color (20th C. pennies & farthings). I have seen some go to a pinkish colour after some while, stripping down to the copper base. Maybe depends on the oil...I remember living on Cyprus and visiting Crete where they had some of the mildest and finest olive oils - I wonder if they were as acid as the base Italian stuff? I remove excess oil with dish detergent and LOTS of water, tamp & not rub dry with a high nap CLEAN white towel. PS - A gentleman in the States, Weimar White wrote I believe two books on coin chemistry and will have a look around and see if I can find at least one title. PPS - Once when I was brave I used a celly charge cord as the power behind an electolyte source to reduce the oxidation at coin surface; believe it or not I found out by this method that one 1936 penny was actually a proof!
