Not sure why you would want to do this, but here is some information from
Pennsylvania DOT website:

USE OF COLLECTIBLE REGISTRATION PLATES

The use of collectible plates is governed by Section 1340 of the

activities, exhibits, tours, parades, occasional transportation and

Permitted use is limited to participation in club activities, exhibits,
