I was looking into Classic tags/registration for my '73 340 Duster, with the option to use a "Vintage" (period correct) License Plate.
Same goes for my '48 Dodge, only as an Antique with a period correct '48' plate.

If you want BOTH the Classic/Antique registration WITH a Vintage plate, PennDOT charges you $75 for the Classic/Antique Registration, plus $75 for the Vintage Registration, plus $22.50 in Title Fees.
The only redeeming factor for Classic/Antique registration is it never expires, and insurance is cheaper... but you're only allowed to drive the vehicle once a week.
Doesn't seem worth it after looking into it. Regular truck registration for the '48 Dodge would be something like $70 a year and insurance is like $40 a month on it and I could drive it every day of the week if I want to.
I know it definitely wouldn't be worth it on the '73, during the summer I drive it multiple times a week.
So I thought, maybe I'll look into "Seasonal" Registration for the Duster & '48...
You pick how long you want the registration to last (example, 6 months) and don't have to keep it registered all year (doesn't make sense to have a vehicle registered for a year, when it spends 6 months in storage due to snow)
Sooo... the first time it'd be registered, they'll prorate the registration for the '48 & Duster based on the amount of months it'll be registered. Seems like a great deal, doesn't it? Your registration fee won't be as much as it is for a regular car or truck, and it's set to expire based on your terms...

The following year, they charge you full vehicle registration price (just like a regular full-year registration), regardless of how many months your registration is good for.
I thought you guys might get a laugh out of that, I know I did.
