I understand that we are interested in anything round that just merely resembles coins (as shopping cart tokens), because we are crazy people, but this?
Well, it is in the bullion section so it is probably okay. There are some coins that are of a similar shape so it blurs the line a bit. Also having it in the catalog will allow someone to see it in their total bullion weight, which is probably why someone added it now that I think about it. I would leave it.
