That's not a "Legacy" Python but a 2020 Python with aftermarket engraving. It may be nice but not worth money any more than a curiosity since it didn't leave Hartford that way. Someone will want want it...that's what the free market is all about. It all never have the future value one might think...as has been said here before...it's a "contrived" collectible.
Whoever buys it...I hope it takes them happy.
