It's not a PSA thing at all ~ but rather a Don Lever thing, that's turned into a collecting obsession. The buyer WILL NOT be out bid for any 1972-73's or any other Don Lever's for that fact ........ and as bizarre as that sounds, it's basically as simple as that.
He buys them all from VG to MT ...... i suspect he owns hundreds of the RC's alone.
So if anybody needs a DL to finish off their set ?? be prepared to dig a little deeper LOL.
