Amazon has a huge issue with sellers mis-representing product, or selling straight up fakes.
EX: This is obviously fake, but clearly being presented as a genuine 1oz .9999 silver Maple. This isn't some obscure listing, it's literally a front page result, #8 for "silver bullion".
Plus, Amazon charges a fee, which sellers just add to the premium, resulting in some of the highest premiums around.
EX: $88 on Amazon, $32 from JM, and this isn't something rare or out of production, it's a 2023 coin that's widely available.
I can't imagine a reason that anyone in their right mind would choose to spend more at a less trustworthy retailer.
