market is thin right now, but anything <10.5 BTC would be dissapointing if its in good condition (It should have like 0.1-0.2btc of altcoins/airdrops if im not mistaken)

A few years ago a silver/gilt coin (1 or 10) had about a 1.5-2BTC premium (the 1oz of silver actually played into pricing!) which has slowly evaporated with time and the change in BTC price.
