It's worth more than $1,000 but I'm much better with older US coins. I see some writing in ink on it which is distracting. With no research being done, I think at least $1,500. Check ebay and Heritage coin galleries for similar.
It's hard to tell by googling it - got them from a friend for 2k - he's had 50 of them - in the 80s and bank manager told him someone deposited em and he gave the bank 50k - he also got 3 10k bills this way - he thinks those r worth about 35k each
Your friend is a better man than I am. He had to of known those worth worth more than 1k. I would do anything in the world for my friends, but just handing them free money isn't one of them. (Unless of course they were in need!)
They are cool as shit! I ebayed it and I did not see one for less than $1600.00. Saw them as high as $5000.00 in mint condition.... Nice...Real Nice....
