History of PR70 Coins
The concept of PR70 grading was initially hypothetical until advancements in quality control at mints allowed for the production of flawless coins. Third-party grading services played a crucial role in certifying the quality of modern coins, leading to the emergence of PR70 markets.

The first coins to receive a PR70 grade were a small number of Proof Statue of Liberty $5 gold pieces in 1986. This groundbreaking event marked the beginning of a new era in coin grading and set the standard for perfection in numismatics.
