Hey everyone...I purchased the chip from Miguel Carlo. Mike is ill and bedridden, he sold off all of his collection to various coin dealers along with his extensive coin collection. This was one of the only chips he had saved and told me he had obtained from a grandson of the person who had worked their. It is the only one known to exist at this time and was not an easy buy but after a while Mike agreed to sell it to me. Other than Mike, myself and Albert Rollins we were the top three in chips in Puerto Rico. I have seen a lot of Mikes chips on ebay being sold by different dealers so somehow a lot of his chips made it to the states...however I know mike had a very extensive collection with rare samples that I have not seen beeing sold anywhere...I am trying to find out where these chips ended up as Mike has no recollection of whom they were sold to. This piece will go into my collection.
