Depends on what you have?
We just watched an auction where a 25btc redeemed went for just under 10k.
brass casascius seem to be consistent at 300-600 range. Although I have seen a few 2011 redeemed sell for thousands. 2k-3k
Silver can range around 2k-5k each, but with the 25k btc selling for 10k....makes me think these silver pieces are highly undervalued.
I haven't seen any bars sell recently. I'd imagine they would be higher than 18 months ago.
Over all I think all physical is undervalued right now, being in a recession with stagflation isn't the best market to sell in.
good luck
