Fair price for whitewall tires

[scar]

I recently purchased a 1928 Model A that has like new 21 x 4.5 Lester
whitewall tires on it. It looks like the spare has never been on the ground
and the ones on the car have very few miles on them.
I don't like whitewalls so I thought that I would sell them. I have a couple
people interested in them, but I don't really know what to ask for them.
Brand new, they sell for $180-190.
Would $130 each be a fair price or is that too high??
thanks
