<p>[QUOTE="DEA, post: 5138775, member: 90140"]Interesting, Ed - [USER=80148]@coin_nut[/USER] ! I'm looking at my KM SCWC (2016 - 43rd edition), 1901-2000 - page 990. It says for a 1906 penny (KM 794.2) - 9.40 grams, bronze (CuSn), 31 millimeters. So, I don't think the diameter or thickness are too out of wack - or not within acceptable ranges. The weight seems a little off but not by much. I don't see anything under Piedfort, Trial Strikes, Patterns, Maundry Sets, Mint Sets or Proof Sets that could explain a silver penny. Intriguing. The only thing I can think to do is taking some time to figure out the density - <a href="https://en.numista.com/numisdoc/determining-the-metal-of-a-coin-27.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.numista.com/numisdoc/determining-the-metal-of-a-coin-27.html" rel="nofollow">https://en.numista.com/numisdoc/determining-the-metal-of-a-coin-27.html</a>.
