I've only received/accepted one sale on a Certified XF Indian $2.5, the remainder are returned "unavailable"!
I watch a couple of dealer websites for gold at spot deals and 1/4 ozt gold does get offered periodically though it's usually the US Mint's $5 commemorative coins and not Eagles or such. For a bullion collector like me, that's perfectly fine.
I tried posting a response that generally when trying to acquire up to/including $50 certified Gold Eagles, "the remainder are returned "unavailable"!" The $2.50 Indian, yet unreceived coin, was acquired at a "bargain price" of ~$625, believed ~25% premium!
