How do rare mint errors affect a Bicentennial Washington quarter coin?
Excuse me, but I'm curious about the impact of rare mint errors on the value of a Bicentennial Washington quarter coin. Could you please elaborate on how these errors might enhance or alter the coin's market worth? Are there specific types of mint errors that are particularly sought after by collectors? And how does the rarity of these errors factor into determining the coin's overall desirability and potential for appreciation?
