I bought some buffalo nickels that are in very good condition. Although, this one is in the worst condition it might be the most valuable? I'm sure it's worth the .25 that I paid!
The lowest price listed is $30 for a VG 10 in a PCGS slab. IMO Your coin is no higher than G-6, (more likely G-4) and it's not in a TPG holder. Look on eBay and see what they're selling for. Here's a list of sold 1920 D Buffalo nickels: https://www.ebay.com/sch/i.html?_fr...ckel&_sacat=253&rt=nc&LH_Sold=1&LH_Complete=1 Please don't respond with the kind of BS like you did in the not too distant past.
1920-D is a good date. But condition is an issue and there is something unnatural about the surfaces of this coin. When a very worn and circulated coin is shiny, that's a red flag. Another details coin.
