I can tell you that certain 1970 quarters are indeed rare and highly sought after by coin collectors. In 1970, the U.S. Mint mistakenly produced a small number of quarters with a design intended for use on the "dollar coin." These quarters were struck over the previously used Canadian quarter, resulting in a unique and rare error coin known as the "1970-S Small Date" variety.
This error is highly valued among numismatists (coin collectors) because of its rarity and historical significance. If a genuine example of this rare variety is offered for sale, it could command a significant premium in the collector's market.
It's important to be cautious when evaluating rare coins and ensure their authenticity and condition by consulting with professional coin dealers, grading services, or reputable experts in numismatics. Prices for rare coins can vary greatly depending on the coin's condition, rarity, and the demand from collectors at any given time.
If there is a specific recent event related to the sale of a rare 1970 quarter on eBay, I recommend searching for up-to-date information from reliable sources or numismatic publications.
