dont buy them i say, here in canada i bought one a while ago , tried to sell it to another dealer at a later date and they said they would give me the 'unrecognized bar' price since banks apparently don't buy/recognize a-mark (yet?). Asked another shop and same thing, reduced rate to buy back, just my opinion, they may and probably are more popular in the US but may want to find out if banks recognize them. of course, it is silver. So if the price is right...
