The silver is peeling off the back of the coin. This may be the highest graded or most well preserved coin exhibiting silver electrodeposition for an Eight Reale denomination. Something that goes beyond Sheffield silver plating as described in the Amazon Gurney/Nichols/Lorenzo (GNL) CC8R book. To be explained further in my new book (Forgotten Coins of the North American Colonies - 25th Anniversary Edition). We see this process starting after 1840 since this process was developed only around this time period (i.e., scientific reference literature checks) and seen in the Cap and Rays Eight Reales series. Difficult to detect if the peeling is not exhibited near the rim areas on UNC/AU examples which may show the underneath base alloy which in most cases like the Sheffield Counterfeit 8 Reales from Birmingham being a high copper alloy. Why this Eric P. Newman coin was not properly cataloged by him as a contemporary circulating counterfeit is unknown - hence the usual - slabbed by PCGS as a regal. Also interesting this coin in hand is like GEM or MS65- reduced I guess to &quot;61&quot; due to this surface effect. INCREDIBLE. Discussed in my new book - Forgotten Book out soon as a new class of counterfeits. Yes- you guessed it - probably hundreds of Cap and Rays which are silver electrodeposited - some may show the indicators near the tops of the rim areas. Silver electrodeposited pieces are different from Sheffield in that this silver deposit is VERY THIN so its more difficult to spot on circulated coins since most silvering may have disappeared or is only detected in small percentages by XRF (i.e., 1-5%) which is often not detectable by the naked eye. Check the TOP OF THE EDGES on Cap and Rays moving forward in all major auction lot viewings for MS60-65 examples for SILVER PEELING and base metal exposure. Robert Gurney is also producing a new book on these Cap and Rays CC&#039;s which is currently in production.</p><p><br /></p><p>John Lorenzo</p><p>Numismatist</p><p>United States.[/QUOTE]</p><p><br /></p>
