Recommend this path; 1. Determine if the coins is an error or damage - most unusual looking coins found in change not mint errors 2. Is the error minor or major - the majority of errors found in circulation are minor and have no additional value. Occasionally you may find one worth a buck or two. 3. If it's a major error, approx how much is it worth it - Sending a coin to a TPG usually cost $50 or more, so it doesn't make sense to send a low value error. Don't jump ahead to step 3 if you haven't answered step 1.
