I am helping a friend liquidate some of his collections and need to determine approximate value of some paper money and coins. In particular, a 1928 G two dollar bill with a red seal and red serial numbers. It obviously has been folded in half and then in half again, but still has a weightiness and somewhat crisp feel to the paper. A couple of the corners are slightly earmarked but the bill is in relatively good condition. Signed by Georgia Clark and John Snyder. To the right and slightly up from Snyder's signature is I515 and on the back to the right of Monticello are the numbers 390. There are no rips in the bill and it is fairly clean. Can you help me determine what it might be worth to a collector or a buyer on eBay? Thanks so much for your help.
