The letter C beside the double strike and then all that weirdness in the side left hand side of the coin, that stuff is probably nothing......but the C and A are definitely errors.....but what kind of value does that put on my coin?

Die crack eh? Methinks you guys are very wrong

I'll post a better picture

Is that a double strike on the A? I'm just not sure where the extra line came from......and if it is an error what kind of value would that place on my coin?

I have an 1872h quarter, already been graded vf+ but then I found what I believe to be am error that has yet to be mentioned on the site here
