I signed the petition and read the proposed law. Among other things, it creates the need for a lot of documentation when selling and buying coins. I assume this is to help provide provenance and track coins that may have been looted or stolen. This is a stupid requirement for the hundreds of thousands of average grade, cheap ancient coins.
This makes me think about my own record keeping. I started collecting ancient coins in the mid 1980s. I have kept most of the sales slips showing how much the coin cost and where it came from. I don't know if this will help me sell my collection someday. Coins from major auction sales and those that are plate coins create provenance. I wonder how much benefit there is in keeping sales slips from Vcoins, ebay, etc. Will potential buyers care where and when a coin was purchased years ago? None of my coins have any provenance older than seventy-five years. In all my years of collecting I have seen just a few coins sold having provenance older than a hundred years.
