Imo I can't image it being worth more then a $1 or $2 in it's condition, but let see what others say.
Guess it doesn't matter. I pretty much concur with the prior statement: Based on the obverse alone, I see this coin on the higher end of the AG3 grade, and since the next grade up (G4, the lowest listed in most references) trends for $4 per Numismedia, you've essentially got a $2-ish coin there, if the reverse is undamaged and not spotted, etc. Let's say $2.50 to $3.00-ish on the high end, to be charitable. Well-worn, but it's from the pre-1886 era when these are a little bit less common.
Too bad about the condition or it's a $5 and up coin. Agree with the others. Prob a dollar, and if you were buying at a store, $2-$3.
