gambling for a card

[aaronjacobg]

I own a Vince Carter signed basketball card with a piece of the court on it. It has been listed in a magazine for $800 but such is the market that one can only sell it for a fraction of the listed price. Recently, I put the card on E-bay and the best offer that i got was $200.

More recently, i offered the card to one of my friends. He offered to play me in one open hand of hold'em for it. If he won i give it to him for free. If i win he pays me $300 for it. Is it worth it? I am heavily leaning towards no so i made him a counter offer. The offer that i made him was that if it was a tie he pays me double, or $600. Am i coming close to equitability? Any other ideas for a deal in my favor?

Thanx
