As the year winds down, were there are any significant error coins minted in 2023 that received noteworthy status and should be saved?
I don't know. But, it would be a good project for someone interested in error coins. I'd like to see a comprehensive list myself.
Well. In actuality, coins in every year could have some type of mint error or variety. You just need to learn and understand what they are and look. Die Cracks, Die Chips and struck through grease are the most common ones. The only interesting issue that I remember for this year was a Die Clash on one of the new designed quarters. https://www.numismaticnews.net/us-coins/major-error-discovered-on-kanakaole-quarter And here's a Cointalk thread https://www.cointalk.com/threads/edith-kanakaole-die-clash.404311/
