Are These Old Bills Worth Any Money?

Unfortunately not; all are common and/or in poor condition.

The only one that might be worth more than face value is the 1938 5 dollar.
Everything else is just too common to have value.

For the 1937 $5 (Charlton BC-23b or Pick P-60b) you might get up to $20 for it. It is difficult to say how stained it is without close-up images of both front & the reverse. Looks like 'VG' with extensive stains to me.

The two Centennial notes (1867-1967 serial numbers) may fetch about $0.25 to $0.50 over FV since they were not only the largest run of any banknote (by BOC) but millions of CDNS hoarded them so very little demand for these. Same can be said for the rest of the notes. The last $2 (Birds) and the last 1973 $1 which appear to be in the best shape. However, bricks & bundles in UNC were stashed by too many people so all of these can be found in GEM condition. They sell for pennies above FV in bundles or maybe 2XFV as runs in UNC. The 1979 $20 is also unremarkable and can be either deposited to a bank (or traded), unless you wish to offer several together as a 'lot' on ebay.
