Roller Marks

Roller marks are thin parallel lines on a coin’s surface, sometimes they’re extremely obvious. Roller marks occur when the planchet alloy was rolled into sheets, the rollers were not smooth and sometimes would create these marks. The strike was supposed to smooth out these marks but this didn’t occur.

These add no extra value to a coin and if extreme enough can actually lower the grade of the coin a point or two and lower the value of the coin.
