Any Idea What This Is Worth?

I have this 1876 gold dollar, I started a date set and bought this in 2002 as a regular NGC MS64, I don't know what designations they used at the time it was graded but after a while I sent int in hoping for a PL or STAR designation and was shocked when it came back DPL*.It's the only 76 DPL and there are many DPLs in the series to begin with, so I can't find any value. It's also from the Garrett Collection, which is nice. It's by far the best coin I have.
A couple pf dealers I emailed said DPLs aren't that big of a deal, since with small mintage coins there would be many, but there really aren't.
There are proofs that are worth a lot, I don't think it would be in that category but still, I wouldn't trade this thing straight up for an MS65,Thanks in advance and this looks like a nice place
