The best way to get price information is to search completed auctions on ebay.
After that, check the offerings of some of the online dealers, such as

These are old and probably of limited coverage. Their value is mostly as
antiques / decorations, though no doubt some photographers are using lenses
like these.

A f2.9 Pentac? This is a WWII aerial lens of varying quality. It probably
doesn't cover 6x8.

This is a fine lens and would have been used by many professionals in the 1950s
and 1960s. The design is the tessar design, which typically has coverage of 55
degrees. For a 10 inch lens the diameter of coverage would be 10.4 inches,
which just barely covers 6x8. In fact, Kodak listed the "Maximum Recommended
Negative Size" for this lens as 6 1/2 x 8 1/2. The price is very high. The
14 inch version is popular for 8x10.

I can't recommend any of these for your cameras. The high-quality lenses that I
see going for very reasonable prices are plain Symmars. 210 mm and longer
should work well for 6x8, 240 mm and up for 8x10. If you want enough coverage
for movements such as front rise, the 300 mm would be an excellent choice for
