: Scammers often claim they "found the coins" and aren't experts to avoid guaranteeing authenticity.

: The safest way to buy is from large, established bullion dealers who maintain eBay storefronts. These sellers are vetted and often provide better shipping rates than independent sellers.

: For high-value items, only buy coins certified by top grading services like PCGS , NGC , or CACG . These holders guarantee the coin’s authenticity and grade.
