Has anyone heard of a 1999 Connecticut Silver Proof error coin? I have been collecting coins for a long time an purchased the 1999 Silver Proof set from the US Mint back when they first came out. I noticed back then that the tree branches possibly had something on the die when it was struck. Now I know since it is a Silver Proof set that it should not have been released from the mint however, it was. I have looked (via internet) throughput the past few years and can not find anywhere there has been another. If anyone has any direction for me I would greatly appreciate it. Thanks??
