Yes Sam you find. This variety issue from Type B Hub and main was use for proof coins. The type H or RDV-008 how you want to say run from 1968 Proof till 1975. In Denver strike are considerate very scarce to rare and it is believe to be issue from one Die and with around 57K strikes. Mainly was find in sets and not in raw in the wild. The most rare is believe to be the 1975-D who it is not confirmed yet to be funded.
For me is missing the 1974 and 1975 and I have hard time to find sets accumulation to buy or just have to study.
It is a very nice addition to the Quarters Varieties Design Collection. Your coin is interesting from the point of view of the Feathers Tail. It is an 1971 and I can see a high reengraved feathers.
