In the Cessna T-37 (Piper type-"Hershey Bar" wing) we did both right side up and inverted spins, though the inverted one's weren't usually intentional.
We never did spins in the Northrop T-38 (Lockheed F-104 stubby, symmetric wing) since it could spin so flat that you were unlikely to get out of the spin unless the aircraft was equipped with a spin chute.
Recovery procedure was: Passing 15,000 ft, Handles-Raise, Triggers-Squeeze.
