About SELMY Graded Coins
At SELMY, we help people sell graded gold coins the way it should be done — with proper appreciation for rarity, condition, and collector demand, not just gold weight. Because the right coin in the right hands can be worth far more than its melt value, our job is to help you unlock the true value of what you own.
Unlock true value
We sell into a wide network of buyers who understand what makes graded coins special — scarcity, eye appeal, grade, and market demand. That means we’re able to price coins as collectible assets, not commodities. If you’ve taken the time to grade your coins, you deserve a buyer who values that properly.
Serious demand & direct corporate relationships
SELMY is built on professional buyer relationships and established demand. We also have direct corporate relationships with companies with demand from serious buyers looking to acquire graded coins.

What Is A Graded Coin?
A graded coin is a coin that’s been authenticated as genuine and professionally scored for its condition by an independent grading service.
It’s then sealed in a protective, tamper-evident holder (often called a “slab”) with a label showing key details like the coin type, year, and grade, helping buyers and sellers understand its value more clearly.
Our Evaluation
Every coin is priced individually based on key factors such as:
Grade & Condition
The certified grade (and eye appeal) strongly influences value.
Rarity & Mintage
Lower availability, key dates, and scarce varieties typically command higher prices.
Market demand
Current buyer demand and comparable sold prices for the same coin/grade guide the offer.
Coin Specifics
Type, year, mint mark, and any recognised varieties or special designations can increase value.
