We are conveniently located on Jewelers' Row in historic Center City Philadelphia, one block from the Liberty Bell. We've been online for over ten years, and have built a large and loyal customer base with our prompt, personal service. Our outstanding reputation is built on years of honesty, trust, and selling quality items at reasonable prices.
CAC
The advent of CAC has led us into the coin business. As collectors, we've always been greatly interested in coins, but unsatisfied with the lack of consistent grading standards. Before CAC we were not comfortable with the grades given to many coins. We would not sell a collectible without the assurance of the grade and therefore value.
CAC provides assurance and comfort to both buyers and sellers, using the industry's strictest standards.
When we sell GIA diamonds, we are 100% confident of the grade as represented on the certification -- the certificate from GIA assures this. Similarly, the CAC designation alleviates concerns that a coin may be inaccurately graded. Customers don't want surprises.

When the owner of a coin decides to sell, there cannot be any doubt as to what is being sold. The grade needs to have already been determined by a third party. There cannot be any question at to its validity. CAC approval makes for easier and risk-free coin buying and selling.
Over the last two years, we have accumulated a substantial amount of CAC coins, originally intended as an investment. However, with CAC certification, we're now excited to share our knowledge and help our customers acquire top-quality CAC coins. Prices have been rising on CAC coins. Collectors are experiencing better returns on their investments with no more guesswork. If you've been curious about coin collecting, now is a great time to get started.
Welcome, new customers! Please contact us with any CAC or coin-related questions you might have.
