Nowdays not that many remember who he was, and the younger crowd would have no clue, so any "name value" on his work would probably be negligible.

Unless you're looking at much more of a desirable "name", like Fitz mentioned above, custom work generally doesn't repay the money put into it, on a shooter.

I'd call it a shooter, not a collector piece, and you can decide what it's worth to you.
Definitely don't buy it as an investment.
