<p>[QUOTE=&quot;dougsmit, post: 1038123, member: 19463&quot;]I really suggest leaving the coin as it is.&nbsp; The black surface appears to be a hard and stable so removing it would leave a rough and porous scrap of copper worthless on the market.&nbsp; The coin looks better than many Parthian bronzes I have seen.&nbsp; I am a little confused by the claim that it was cleaned by electrolysis since this usually removes patina along with the crusts so either the cleaner was better than most or the coin has been artificially retoned.&nbsp; Either way it looks better now than it would scrubbed down to new penny brightness.[/QUOTE]</p><p><br /></p>
