YES this is a great Seinfeld item that you don’t see often (I never saw it before).
It is a keychain of Del Boca Vista, the retirement community where Jerry Seinfeld’s parents live. But this key chain is from his dad because it has a special metal coin saying Mortimer Seinfeld.
So by owning this key chain you have two unique items that a real Seinfeld fan can’t live without.
Check out this Seinfeld Del Boca Vista Keychain.
