The envelope was machine stamped and had two 41c stamps on it. The seller is a great guy and club member. He gave me a full refund, told me he would put out the word to try to find another chip for me and even offer a 1/2 reduction on my next future e-bay sale. For now the broken chip will get super glued together and fill a hole in my collection until a replacement chip can be found. A happy ending but still a chip missing from my collection.
