Not verified, no rankings, not even actual photos of "your product"... Are you just reselling others actual products as if you own them?

Junk silver is just that, junk... No-one will give you anything more than the price of aluminum for it, until it has been smelted and had its contents confirmed to determine the actual silver content within. You are admitting they are 90% junk, so they are worth less than 2% the weight of silver. (Would take more to melt them down, and process them, than they are worth, in silver.) You offering some publication, of tested material, since you "claim" they are 90% junk, or are you just guessing they are 90% junk? Or did you just copy that off of another person's webpage, so you could make a sale, and seem like you actually know the content-level?

You do realize that silver (coins), are a future-sale, which won't be worth the price of silver-content within, for well over 20 years. (Unless silver triples early.)

What "proof", since you don't have "credentials", are you offering as "trust" for these transactions? Are you allowing the use of an escrow service, or offering some additional "personally identifiable, and prosecutable, information" beyond the posted sale-page?
