In general, the majority of these quarters have a face value of 25 cents and do not hold significant numismatic value beyond their monetary worth. As long as they're genuine, non-defective, and not part of rare mintages, quarters with Elizabeth II's portrait, regardless of the year of issuance, typically retain their 25-cent value in terms of exchange.
Some variations or special issue quarters, however, may carry higher value and interest based on specific collecting considerations, such as errors, limited mintages, commemorative designs, or unique finishes. If you have reason to suspect that your quarter might fall under a rare or special category, researching collector markets, seeking out professional numismatists, or checking authoritative sources on coin values will be helpful in assessing whether it holds collectible value beyond its face amount.
