Curio And Relic

I just registered something...

To be recognized by ATF as a C&R firearm, a firearm must fall into at least one of the following three categories:

1. Firearms which were manufactured more than 50 years prior to the current date, but not including replicas thereof;
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. Proof of qualification of a particular firearm under this category may be established by evidence of present value and evidence that like firearms are not available except as collector's items, or that the value of like firearms available in ordinary commercial channels is substantially less.

Isn't the present value of every pre '86 transferable because of the Hughes amendment, and therefore derive a substantial part of their monetary value from being rare?

I am tickled that every transferable could be a C&R eligible gun (yeah I know they're doubtlessly ruled as not).
