Can you give me an example?
Why would anyone want to trade precious metals for precious metals?
Do you mean like trade different year coinage for your collection, or trade Indian Heads for silver?
Right now we're having a really hard time controlling all the ads for coinage. Members seem to want to part out their collections so we've had to limit each member to one thread. Originally Classified was meant only to sell equipment and finds.
Plus, we have complaints from members who are tired of browsing through all the coinage ads just to find equipment.
Personally, I think that all the coinage ads would do better in What's the Value, since that's where we talk about coin collecting, but I can't seem to get anyone to agree with me.
I know this didn't answer your question. But I need an example.
