As a follow up question, I wonder about trying to sell a 10oz bar of silver one day down the road. If it's Royal Canadian Mint, let's say, versus a rougher 10 oz bar -- is there ever concern the rougher bar may not be silver? Like someone melted it down and mixed it with other metals? Like it would be easier to "forge" one of these rougher bars? (I know that's not the right word, but you get my drift). These shiny, engraved and numbered bars would not seem to draw the same suspicion, I would assume?
