I come across a few badges and pins each week buying scrap gold lots and at estate sales have a few on ebay now. If you are interested in any of the listings on ebay and they take best offers look up the spot price of gold and offer 40% over spot since on ebay after the close to 20% they take in fees as a gold seller the 20% profit is enough. most of the time I end up melting them down though since interest in them is low. If there was more of a market for them I would go ahead and pay spot on them and buy more of them.
