About CoinDuffle
CoinDuffle is a marketplace built for collectors and investors who want a transparent, secure way to buy and sell rare coins, bullion, and precious metals.
Our Mission
The precious metals and numismatics market has historically lacked transparency. Prices vary wildly between dealers, authenticity is hard to verify, and trust is difficult to establish. CoinDuffle exists to change that by connecting buyers directly with vetted dealers on a platform with live spot pricing, authenticated listings, and secure transactions.
Trusted Dealers
Every seller on CoinDuffle is vetted before they can list. We verify credentials, track performance, and ensure buyers are protected.
Live Spot Pricing
Bullion products are priced dynamically based on real-time spot prices, so you always know you're getting a fair deal.
Community Driven
Built by collectors, for collectors. We listen to our community to continuously improve the buying and selling experience.
Secure Transactions
Payments are processed through Stripe with full buyer protection. Every transaction is secure and backed by our returns policy.

- Rare and collectible coins from trusted dealers worldwide
- Gold, silver, platinum, and palladium bullion at live spot-based pricing
- A buyback program with instant offers based on current market prices
