Fred,
This appears to be a nice old ax head, possibly from the time period stated in the description. The seller says that he is not representing it as being George's ax. I suspect it will bring a pretty good price, but not as if it could be proven that it really was George's ax. Its construction features and the fact that it has the English broad arrow mark should excite some collectors. Most collectors will see past the unproven "George Washington" connection and will bid on it for exactly what it is, a very nice old collectible ax head. I would think that it will bring $200 - $300 dollars and possibly more.
