Asked Questions

ABOUT CONSIGNMENT

Coin grading is the process of evaluating the condition and authenticity of a coin. Professional grading companies like NGC and PCGS assess the coin’s physical condition on a scale from 1 to 70, with 70 representing a perfect coin. Grading provides collectors and investors with an accurate, impartial assessment of a coin’s value.
Grading your coins offers several benefits. It authenticates the coin, ensuring it’s genuine, and provides an accurate assessment of its condition, which can significantly affect its value. Graded coins are also encapsulated in protective holders, preserving their condition over time. Additionally, graded coins are often more attractive to buyers, making them easier to sell or trade.
Our Coin Pickup service is a convenient and secure way to start the grading process. We can arrange a fully insured pickup from any location you choose, ensuring your coins are safely transported to our facility without any hassle. This service is designed to provide you with peace of mind from the very beginning of the grading process.
Once your coins are picked up, we handle the entire submission process for you. This includes securely shipping your coins to the United States, navigating customs, and completing all necessary forms for submission to NGC or PCGS. We take care of the details, so you don’t have to worry about anything.
Throughout the grading process, you will receive automated email updates directly from NGC or PCGS. These updates will keep you informed at each stage, from when your coins are received to when they are graded and ready to be returned.
During authentication, NGC or PCGS experts verify that your coin is genuine. They compare the coin to known standards for its type, checking details such as weight, diameter, and design. This step ensures that your coin is not a counterfeit or altered.
The grading process involves evaluating your coin’s condition on a scale of 1 to 70. Professional graders examine factors such as luster, strike quality, surface preservation, and eye appeal. The coin is graded by multiple experts to ensure accuracy and consistency.
Encapsulation is the process of sealing the graded coin in a tamper-evident holder. This holder protects the coin from environmental factors and physical damage. It also includes a label with the coin’s grade, certification number, and other important details.
The time it takes to grade a coin can vary depending on the service level selected and the current workload at the grading company. Typically, the process can take several weeks from the time the coin is received by the grading service.
After grading, your coin is encapsulated and its details are entered into the NGC or PCGS database. We then securely return the graded coin to you, along with a detailed grading report. This ensures you have all the information you need about your coin’s condition and value.

Yes, both NGC and PCGS maintain online databases where you can verify the grade and certification of your coin. Simply enter the certification number provided on the coin’s holder to access its grading information and images.

If you have any further questions or need assistance at any stage of the process, our customer service team is here to help. Please don’t hesitate to contact us for more information or support.
