Found this oddity roll hunting. Was surprised to see the wood grain appearance on a modern quarter which is a first for me. I have only seen this texture on improperly annealed pennies. But to date not on any clad coinage I have searched through. I am seeking affirmation that this is a verifiable mint error and not the result of environmental exposure worth nothing more than face value. My hopes are high there is value as a collectible and has potential on the market. Given the type of coin and definite eye appeal knowledgeable opinions are most welcomed. This includes an opinion that may burst my bubble.
I agree with roller lines. Also known an roller marks...
roller marks Term to describe the mostly parallel incuse lines seen on some coins after striking. These were originally thought to be lines resulting from debris "scoring" the metal strips before the blanks were cut. However, new research has pointed to the final step of strip preparation, the draw bar. To reduce the strips to proper thickness, the final step was to pass them through the draw bar. It certainly seems logical that debris in the draw bar may cause these lines, if so, then draw-bar marks or lines would be a more appropriate term.
