Sorry for the quality of the 2 pics, I took them with my PS Vita. http://prntscr.com/7pagnx http://tinypic.com/r/2coj1up/8 I got it from my brother for $20. (It looks like there's a bit more in the pics, or whatever, though.)
How the fuck do we know? We don't know. Here's why: We don't live where you live so we don't know what the prices are where you live. The internet hasn't come up with a way to weigh things by looking at a picture. That's not a very good picture, but that's beside the point. See above.
I think it's worth 16 dollars, 4 pennies(all newer then 1994) ,some pocket lint, a stick of gum, and this marble I found.
