vintage Mags questions

I have some wheels from a house and garage that was being torn down in the neighborhood. The guy had a 67 GTX:
I have a pair of Torque Thrust style 15" x 6" 5bolt 4.5 (if I am measuring correctly)
can't find any markings on them;
Also I have 6 Magnum 500s: (same size)
2 of them are very good condition, 2 need small bit of work near rim, and 2 of them are good but have these weird holes on the outer edge?
I will be selling them but don't know what they are worth? in unrestored condition.
thanks for any info
