Greg, as said above, values can fluctuate, many shops don't realize that lugers must be matched (most small parts).
Posting detailed pictures would be the easiest thing. Although You could send them to me, and I'd appraise them for you, no cost, send via USPS and they'd be here in Pennsylvania in a day (I have an FFL 03, but have access to an FFL 01) and if as nice as stated, we'd give an honest buy it price along with the retail price (for insurance / selling etc.
A gun shop price of $960 was a bit low if all matching and nice, but higher than I have seen many times
