If it were me, that would be a candidate for Verdicare, but looks very superficial so try a dab of acetone first. Jerry

Any chance of a photo, Peckris? For localised verdigris I have found Verdicare very useful, to the extent of full removal, but it does require time for the drop applied to the verd to soften it, and mechanical prodding eg cocktail stick to remove it, and may need repeat application over a few days. As stated before high magnification and a steady hand are appropriate. Next time I tackle one I will try and take photos. Jerry

Well done! A little earlier than my guesstimate, a nice find! I actually like these, though I don’t collect them I do find them occasionally. They can be bought quite cheaply at coin fairs and on the net, and have some very pleasing designs. Jerry

It is a Continental Jetton, probably sixteenth to seventeenth century and probably from the Low Countries. There are many varieties, have a google. Jerry

One would have to exclude oxygen during the soaking process or the oxidation of the oil will happen. Of course the acidic effect on the coin is what gently removes the patina and initially can make it appear nicer. The difficulty is removing the olive oil fully afterwards, impossible if a heavily patinated coin has had a prolonged soak. There are academic articles on this that I have read in the deep past but I can’t remember where. Perhaps in a conservation publication. Jerry

Thankfully very inert, at least as far as metals are concerned, I’d even use it in my cars! The copper alloy parts in my 60 year old Landrover carburettor remain pristine, if a little worn. Any worries of even long term coin damage are misplaced, and this applies to most of the easily available organic solvents, though as stated above I always use a precautionary 100% acetone wash as a final step. Olive oil, widely used apparently on coins, is far worse as it oxidises into an acidic compound which does have damage potential. And the waxes and oils that accumulate around the details of handled coins likewise are sources of the salts that initiate and maintain verdigris, letting those deposits remain is itself a long term risk, and the main reason for the development of verd for example on slabbed coins. Jerry

Interesting that the Hadrian is a plated coin, probably though not always I understand a contemporary forgery. The original coin is indeed a denarius, it looks largely to have corroded to horn silver. Nice finds. I haven’t had a denarius for several years, but did find a superb siliqua of Magnentius on a club rally in 2017. Jerry

What I mean is the deep chested, short legged style of horse. Was there a moneyer Thelwellius? But a denarius or copy remains quite possible. Obverse please. Jerry

The style of the horse and rider isn’t particularly Roman, and it would be unusual for a denarius to become quite so corroded; can we see the other side? The portrait should be reasonably discernible if the horse is. Jerry

Phew.....you didn’t.

Don’t do it Rob!

It is a French Jetton, very similar to Barnard 7a, (Barnard, The Casting-counter and the Counting Board, 2nd ed Fox 1981); ”A man standing, full faced, under a decorated canopy; he has long hair, and wears a wreath of roses and a 14th century jupon; in his right hand is a rose bush (?), in his left a garland of roses; below his left elbow is a large rose or cinquefoil; all surrounded by a granulated circle from which issue eight cusps; his feet pass beyond the circle and rest on an exergue ornamented with small crosses. Legend SVR.MA.TEST E CHAPEAVD . Rev as that of no 7, but reading T V E M. T.C.R.,I, No 1401” The reverse 7 quoted is as yours, but for the letters AVEI, yours appears to read AVEO. The reference T.C.R refers to a series of catalogues in French around 1900 by De la Tour. Jerry

Except that it is much more effective than acetone at softening or dissolving the waxy residue around the lettering on some of our well handled bronze, enabling it to be gently removed with a soft brush. To be fair I only do this sort of thing under high magnification using a binocular microscope, the same one I use for archaeological conservation work. IPA, DMSA and Industrial meths also seem inert as far as the coin is concerned. Petrol of course has a multitude of additives, and to be safe the coin needs a wash in acetone after treatment. Don’t knock it if you haven’t tried it, most collections (not yours of course Pete) will have a dirty and inexpensive coin to practice on, and get a fine artists brush and cut the bristles to 1/4 inch. Jerry

Petrol will work in most cases, followed by a wash in pure acetone, neither of these will alter the coin physically. But most important is not to rub the coin surfaces, nothing more than a dab with clean cotton wool or soft artists brush to wash away any softened residue. As ever, practice first on a less valued coin. Jerry

Shame we can’t report people for being a PRATT! Jerry

Report under ‘Prohibited and restricted items’ then choose ‘Stamps, currency and coins’ then you have a choice including ‘Replica coins, replica currency, replica stamps’. Jerry

Report please. His Charles shilling is a replica too. https://www.ebay.co.uk/itm/Very-Rare-Edward-6th-Hammered-Silver-Shilling-C1549-1550/323505234992?hash=item4b526a2430:g:-WIAAOSw0W9byGdB Jerry

Ouch! I would try and find a way to pay promptly, their terms appear fairly strict (though I have no personal experience of them) and I suspect any default would work out expensive in the long run. Can you not eliminate the wire fee by paying with PayPal, as a ‘gift’ if necessary? Even a standard PayPal fee would probably be cheaper than the wire charge. They give the sale price as $336, I presume this includes the buyers premium? Nice coin though. Jerry

Spotting that it is the only example in a database of 500 sounds pretty good research to me! And a good buy for 100 Euro I would say, whether or not it currently attracts a premium, it probably will when you have finally published your study. Jerry

Yes, I saw that on Numisbids, but a few hours after the auction! Correctly described, but wonderfully cheap! Well done, I wondered if it would find its way back to the UK. Jerry

And done.

It can only have been made out of two separate coins, as the halfpenny has been struck within a collar - it has an outer edge. Somebody has been playing about with a lathe. It has no numismatic value. Jerry

I assume that when there is a genuine bid, but below the reserve, they have to introduce a ‘house’ bid before they can knock the item down, otherwise the genuine bidder might think he has won the item. Not an issue when there are no bids at all, of course. Jerry

Also don’t forget the RM might still have the original dies............ Jerry

Yes, this is one of the other differences between the two reverses. Well done on the ‘shuttle’ penny, you must look at a lot! Jerry
