NGC also provides numismatic certification to ensure that collectors can verify the authenticity and quality of their coins.

Frequently Asked Questions
How Long Does NGC Typically Take to Grade and Return Coins?
NGC’s typical processing times vary based on service level and submission volume.
Standard grading takes 20-40 business days, while expedited services like “Express” or “WalkThrough” range from 1-10 business days.
Bulk submissions generally require 30-60 business days.
These timeframes commence when coins arrive at NGC’s facility, not upon system entry.
Factors like seasonal demand, submission complexity and postal delays can affect overall turnaround times.
What Happens if a Coin Gets Damaged During Ngc’s Grading Process?
If a coin is damaged during NGC’s grading process, their guarantee provides compensation based on the coin’s fair market value.
NGC thoroughly assesses reported damage to verify it occurred during their handling. Submitters must promptly report suspected damage after receiving their coins.
Following internal review, NGC may offer monetary reimbursement or replacement.
However, the guarantee doesn’t cover pre-existing damage or issues highlighted before submission.
Can NGC Grade Coins That Have Been Cleaned or Chemically Treated?
NGC cannot assign numeric grades to improperly cleaned or chemically treated coins.
These pieces receive an “NGC Details” grade instead, which notes their condition whilst acknowledging the alterations.
However, some chemical residues can be safely removed through NGC’s professional conservation services, potentially improving grading eligibility.
Permanent surface changes from improper cleaning or chemical treatments will always result in a Details designation rather than a numerical grade.
Does NGC Offer Bulk Submission Discounts for Larger Coin Collections?
NGC offers extensive bulk submission discounts for larger collections, requiring a minimum of 100 coins of the same type per submission form.
These discounts are particularly advantageous for Collectors Society Elite members, who receive reduced grading fees compared to standard rates.
Eligible coins include US Mint State, Proof, and specific World Coins.
Bulk submissions can be up to 200 coins per form, with fees starting from $5 per coin depending on type and tier.
Can International Collectors Submit Coins Directly to NGC for Grading?
Yes, international collectors can submit coins directly to NGC for grading by becoming NGC Collectors Society members.
They must follow specific submission guidelines and secure packaging requirements for international shipping.
However, NGC recommends using their authorised submission centres or regional offices worldwide for more convenient processing and reduced shipping costs.
These local centres provide language support and help navigate import/export regulations whilst ensuring compliance with NGC’s standards.
