Pumpkin- there are several different classes of Federal Firearms Licenses in the US- 01 is a dealer, 02 is a pawnshop, and an 03 is a collector of Curio & Relic firearms. C&R is defined as a firearm that derives most of its value from its collectable status. They include firearms that are 50 yrs old, or older, and cetain newer guns on a list published by the BATFE, such as all Winchester Mdl 88s, All Colt Woodsman pistols, etc. License is $30 for 3 years.
Lets say I find a refined gentleman from the Pacific Northwest- I live in VA. He has an M1 carbine he wants to sell to pay his gambling debts. We come to an agrement on the price. I send him a photocopy of my FFL and payment. He puts carbine in mail to my door. Mailman delivers. I scurry around trying to hide rifle so I don't have to play the "What? This old thing?" game with Household 6 (wife). No dealer required.
Most fun you can have for $30 that will not require antibiotics to fix.
