Welcome, Coin Collectors and Investors!

National Watch and Diamond, a family owned and operated business, has been located on Jeweler’s Row in Center City Philadelphia for twenty-five years, selling high-end, pre-owned watches, GIA-certified diamonds and fine jewelry. We are excited to now offer CAC approved coins to our clientele.

Better coins are expensive and therefore we believe that collectors and investors should purchase those that are most accurately graded. We cannot understand why coin buyers would not want the added assurance of CAC approval. Massive over-grading has been prevalent for many years. The CAC sticker alleviates any doubt as to the actual grade of the coin. When the owner of a coin decides to sell, there cannot be any doubt as to what is being sold.

National’s reputation for honesty, quality, and service is impeccable. We pride ourselves on selling high quality merchandise at reasonable prices.

Due to insurance reasons, the majority of our coin inventory is stored off-site. However, if you are planning a trip to Philadelphia, please call ahead and we will be happy to make our inventory available to you at the store location.
