sound Posted September 7, 2013 Posted September 7, 2013 Hi, Deep into pennies at the moment.Lustre has a lot to do with valuation. Question: what is it? I know what I think it is but the web supplies conflicting ideas. For example, the ability to reflect light as per original strike. Another site says colour.RegardsSound Quote

As it wears, that special surface disappears and so the lustre gradually goes. It does vary a lot in colour, but think of it more as 'reflectivity' and you won't go far wrong (though 'colour' is generally how it appears to the eye). Quote
sound Posted September 7, 2013 Author Posted September 7, 2013 Thanks, that's my understanding, you just put it so well.So a virtually completely toned Victorian penny can still have full lustre?Sound Quote
Coinery Posted September 7, 2013 Posted September 7, 2013 Thanks, that's my understanding, you just put it so well.So a virtually completely toned Victorian penny can still have full lustre?SoundYes, and be quite dazzling for it too, a rich shimmering tone! The one very important thing to remember is lustre-shine and reflectivity are not the same thing as a shiny coin, which will likely be cleaned or polished!Lustre has a luminance about it, definitely 'shimmering,' whereas a polished coin most certainly does not!Welcome aboard sound!

sound Posted September 8, 2013 Author Posted September 8, 2013 Is the removal of lustre caused by handling alone? Quote
Peter Posted September 8, 2013 Posted September 8, 2013 Is the removal of lustre caused by handling alone?Not in my experience. Quote
Colin G. Posted September 8, 2013 Posted September 8, 2013 Storage conditions can also have a major affect on lustre, in my opinion lustre can be removed by other factors.. Quote
sound Posted September 8, 2013 Author Posted September 8, 2013 Ok. Can you explain further?If I was to purchase a coin with 100% lustre. As the lustre deteriate s presumably my coin is losing value.What will cause it to lose lustre, how can I protect it?RegardsSound Quote
Peckris Posted September 8, 2013 Posted September 8, 2013 Is the removal of lustre caused by handling alone?Well that's a complicated question. Circulation is the biggest factor, but also environmental conditions must be taken into account : burial, salt air on coasts, poor storage (PVC), etc etc. But stored adequately, a coin's lustre will last indefinitely, though it may tone and/or fade. But it is still there, technically. As Coinery says, a shimmering but toned coin (copper/bronze) can be fully lustrous!Just make sure you store properly - PVC-free plastic flips, cabinets, trays are the best. Keep free from environmental pollutants, but don't get too hung up about lustre fading or toning. It's not the same as circulation wear, and only the money of determined but ignorant buyers will say otherwise. Quote
sound Posted September 8, 2013 Author Posted September 8, 2013 Peckris,Thank you for that. Just the clarification I have been looking for.I store my coins in the purpose made capsules in a dry, dark safe at room temperature.Thank you all. Much is written about grading but noticed little said about lustre. Yet it seemed so important in connection with copper & bronze.Kind regardsSound Quote
Coinery Posted September 8, 2013 Posted September 8, 2013 Quality-strike and lustre (and sometimes tone), is a lot of what it's all about, Sound, for the silver, CU, AU, and Coppe/Bronze collectors ! It's the holy grail for as far back as it's possible to get a lustred coin, whereafter tone becomes the measure. Quote
Colin88 Posted September 8, 2013 Posted September 8, 2013 A damp atmosphere is one of the biggest killers of lustre...the best thing to do is to sell your house and move to the South of France... Quote

Peter Posted September 8, 2013 Posted September 8, 2013 Plenty of thrupenny bits on the beaches go round and oil these. Quote
Peckris Posted September 8, 2013 Posted September 8, 2013 Plenty of thrupenny bits on the beaches go round and oil these. Wasn't there a Peter Perv on Blue Peter once upon a time? Quote
copper123 Posted September 8, 2013 Posted September 8, 2013 yes and Ann Robinson accused him of killing shep - the evil bitch.And it was purvis I think all the pervs were on top of the pops after legs and co - or maybe something a bit younger Quote
