I wish I had your same problem on prices mine are way over anything you have listed. I would say the Bernie Mirror Gold is not too far off his asking price I would think $1000.00 to $1,200 it would sell for if it went on auction. There was a 1993 Finest Refractor sold for almost $300.00 ungraded and I think the Mirror Gold would be more sought after. It's hard to gauge seeing they don't sell often and a card is only worth what someone is willing to pay. If you want it bad enough you will pay the prices if not then you won't own it unless you get lucky and find one on a auction. I know how people feel I felt a card was too high as it was listed with a starting price of $250.00 a long time ago and I offered him $225.00 he passed put it on auction starting at $0.99 and went for almost $400.00. Now I wish I had just paid the $250.00 as I still don't own the card. So really they could sell if the person wants it bad enough especially the ones that are crazy rare like 1 to 5 made.
