Silver Dane, please do not use text lingo here. I know it comes naturally to many people these days, but our members span the globe, and many have to use translators to read the forum. Things like "u", instead of "you", do not translate well, so it is against forum rules.
AP may not dissolve all the copper. It may reach a point where the silver that remains may keep the AP from reaching the core of the coin. Think about a sponge. If it is put into a solution, the outside of the sponge is exposed to the solution and the solution can readily circulate in the outer layer, but deep inside the sponge there is little circulation. I've never tried it, but I expect there could be some copper left in the inner core.
