1999 P Nickel With Off Center Strike

Nice Off Center! I'd say a price of 40 dollars sounds right.

Apologies if you know this already (I don't want to be overly pedantic) but grading refers only to the overall condition of the coin, while attribution refers to naming of the error or variety present.

You have to pay for both services if you want the TPG to label them, and that raises the cost substantially.

Generally, collectors of high grade coins don't care as much about errors and collectors of error coins don't spend more to get a high grading example.

If someone wants a nice example of an off center strike like yours they don't need to pay for a professional to tell them it's an off center strike, because that's obvious.

I'm generalizing, of course, as rare errors and very high grade coins with errors are worth more, but it doesn't automatically add the value you might think.

Great off-center strike!

Very nice!
