I was looking at dropping them off at any of the bullion dealers in Melbourne CBD, but it looks like they only buy at spot minus a premium (ouch).
I keep thinking surely my coins are worth more than spot, cos they're either proofs, or first/early releases of low mintage sets.

To get an idea of a fair price I've tried to look through the forums here at "WTS" posts, but it kinda looks like no one is selling, so it's hard to figure out.
Would anyone have any idea what is a fair price for these?
Spot minus premium?

By the way if anyone here is interested in buying today or tomorrow I'd be happy to meet F2F

Parabolic chart shows difficulty of price discovery for premium bullion.
check websites and filter ebay lists for sold items but until chart tapers forms a base and consolidates for a good 6 months we'll surely tread between either seller or buyer being decently ripped off and that perception depends on which eyes are asked. if two people can strike a deal and lose no sleep thats a fair one
