i am looking to invest in Silver Pandas, but am not really clear on these items. so far, i have only seen "proof-like" silver pandas, but to me, they look like it has all the qualities a "proof" coin should have, and then some. but a lot of stores/sellers like to call them "proof-like"? so, if the coin is not U.S. made, then it is "proof-like", "cameo-like", "clad-like"? anyways, if they exist, i would like to purchase regular non-"proof-like" Silver Pandas if there are such things, because otherwise, they are far too expensive to buy as a bullion-silver investment.
