50 Years Old is a Curio or Relic.

To be recognized as C&R items, 478.11 specifies that firearms must fall within one of the following categories:

1. Firearms which were manufactured at least 50 years prior to the current date, but not including replicas of such firearms;
2. Firearms which are certified by the curator of a municipal, State, or Federal museum which exhibits firearms to be curios or relics of museum interest; and
3. Any other firearms which derive a substantial part of their monetary value from the fact that they are novel, rare, bizarre, or because of their association with some historical figure, period, or event.

Firearms automatically attain C&R status when they are 50 years old. Any firearm that is at least 50 years old, and in its original configuration, would qualify as a C&R firearm. It is not necessary for such firearms to be listed in ATF’s C&R list. Therefore, ATF does not generally list firearms in the C&R publication by virtue of their age.
