<p>[QUOTE="dougsmit, post: 4682623, member: 19463"]I wish there were an easy answer to your question. I bought this shiny silver denarius in 1988 from NFA where it was described as ex. Brauer collection. Over the years it has not toned but has darkened the black spots over the head on the obverse. My assumption is that it was brightly cleaned and then treated with something to slow tarnish. Since 1988, I have went through several changes of holders including about 20 years in trays with other coins that darkened more than this. I have other coins from that period that are now prettier than they were. In 1988, I photographed coins using a film camera and now only have tiny 'contact' prints to show what the coin looked like then. I recall almost not bidding on this one because it was so bright but assumed it would tone down in a few years. I'm waiting, still. Perhaps I should try an acetone bath hoping to remove whatever is preserving the shine. On the other hand, I could take my own advice and trade coins with someone who likes it as is and get one that I like. Best wishes for your coin 'progressing' faster than mine.</p><p>[ATTACH=full]1152564[/ATTACH][/QUOTE]</p><p><br /></p>
