Looks close to full detail, but the cleaning/polishing is bad enough to really hurt. Good date though. Maybe worth F12 money, maybe a couple hundred bucks? Things like this can be hard to value, trying to find something similar on eBay's sold listings would be one source.
This is a great coin for someone who needs to fill a hole their sets on a budget. It would be interesting to see on a no reserve auction.
Low grade AU details (probably a 50). Coin is so heavily cleaned it is a damaged coin. Worth less than half of going rate for a very good date.
