Hi @Aberdumbie,
Thank you for contacting us. We do offer a reholder service where a coin can be placed into a new holder. The fee is $13 for coins valued up to $10,000, and $50 for anything valued above $10,000. Details can be viewed at NGC Reholders. A paid membership is required to submit reholder service. Membership tiers and pricing can be found at Join NGC. Please note, the grade assigned to the coin should not change, unless any damage occurred post-encapsulation, in which case the grade will be adjusted accordingly. To qualify, the coin must still be encapsulated in its original NGC holder.
If you have any other questions, please let us know. Thank you!
