A cud is where a piece of the die completely breaks away. Leavin a big blob on the rim. Check out cudsoncoins.com for value and rarity.
The site you attempt to link is all advertisements. The correct link is http://cuds-on-coins.com/ OPs coin doesn't seem to appear on cud-on-coins. A new one?
Would you mind posting a photo of the obverse? I'd like to see if a weak strike is evident due to the lack of metal flow. Chris
BTW, it's actually a 1983-P. Not seeing it here: http://cuds-on-coins.com/washington-quarter-cuds-1932-1999/
U think so it's so hard to tell but I think it's a 2 but I didn't see it there either but ok I used a Jewelers scope and yes it does look like a three thanks
I'd keep it. I have no idea of its value. Someone with more knowledge than I might come along to tell you what it's worth.
