IDC Verified combines the experience of IDC's numismatists with third-party authentication and grading through Independent Coin Graders (ICG).

The precise certification designation depends on the type of item being evaluated.

Understanding Authentication & Coin Grading
Authentication and grading are related but distinct. Authentication concerns whether an item is genuine. Grading describes a collectible coin's condition.
| Designation | Meaning | Typical Application |
|---|---|---|
| Genuine | Authentication designation, not a numerical grade | Eligible coins, bullion, or specialty items |
| AU-50 to AU-58 | About Uncirculated condition grades | Collectible coins with slight circulation wear |
| MS-60 to MS-70 | Mint State numerical grades | Uncirculated collectible coins |
| AU Quality / BU Quality | Descriptive condition terminology | Items without a specific numerical grade |
| Details | May identify a genuine coin with a noted condition issue | Coins with cleaning, damage, or other qualifiers |
An ICG Genuine gold bar is not equivalent to an MS-70 gold coin. Buyers should review each product's specific certification information.
Why Collect IDC Verified Coins & Bullion?
Historical Significance
Historic coins connect collectors with American monetary history, classic coin designs, and former mint facilities.
Independent Evaluation
ICG certification provides an independent opinion regarding applicable authenticity and condition.
Precious-Metal Content
Gold, silver, platinum, and palladium products may carry intrinsic precious-metal value.
Numismatic Interest
Date, mintmark, variety, rarity, preservation, and collector demand influence collectible value.
Certification can provide additional information, but it does not guarantee a particular market value or future appreciation.
How to Choose an IDC Verified Product

IDC Coin & Bullion: A Numismatic Heritage
International Diamond Center traces its origins to 1981, when the business began as a coin and bullion dealer.
The company later expanded into jewelry and diamonds, opening its first Clearwater, Florida, retail location in 1990.
In 2007, IDC returned to its numismatic roots by establishing IDC Coin & Bullion as a division specializing in rare coins, collectibles, and precious metals.
The IDC Verified program builds on that history by combining IDC's numismatic examination with independent ICG authentication and grading.

Customer Reviews
"Amazing service and hospitality from the staff at IDC! Jason was so attentive and patient in our search for our ideal watches. He took us through several options, had us try every watch we were interested in, took our information and continued searching for options. A few hours later, we had our watches on hold and ready for pick up! He located a watch that I LOVE, and a unique piece for my husband. We are grateful to have found our new Jeweler for many pieces to come!"
