How much did the 2008-W (Proof 4 Coin) Gold Buffalo Set cost from the mint? APMEX is selling the proof set for $7,995.00.
The "W" mintmark coins are the collectible versions, not bullion, per this forum. You need to get this question in front of elaine1970. She should have the figures posted on CT somewhere, but probably buried in her threads.
It was a while ago, but I think I paid about $1800 per set. The fractional Buffalo Gold pieces now are "stupid money".
For the OPs reference if interested, a thread from February 2010: 2008 W Series to Signicacanlty drop in Value?
