here is a picture instead of a scan if this helps, the reverse has what appears to be a rim connecting to another one but not sure
not the side thing silly... the encased, anyhow I will try and take a picture of side it looks like the rim edges are thicker then the center
Sorry....sometimes I read too fast and miss things.... Anyhooo, check this out: http://www.encasedcollectorsinternational.org/
oic, do they add extra copper to rims to do that? my coin looks like when you use a cookie cutter and there was to much dough causing excess out the sides it is not even all the way around
Read under the chapter "How They Were Made". There's a good explanation as to why the edge appears as it does. http://www.encasedcollectorsinternational.org/Articles File/Collecting Encased Coins.htm
It looks to me as if may have done some heavy cleaning between post #1 and post #4, or it may just be the angle of the photos. Did you clean the coin from the first set of pics to the second? If you did clean it and it had been a coin of some value, cleaning could cause a huge drop in value or even cause the coin to be worthless to a collector. Ben
