I have noticed, and you can look at past sales on the forum. Doesn't matter if they are factory "black" wheels. Factory wheels (from previous history) are not selling for an outrages price, when someone could spend the money to get 20x10. Secondly, these are from a 2013 (they have seen 3-4 years of weather - I am willing to bet there is probably faint hairline scratches just from everyday road debris; heck my 17' is only 3 months old and there is very faint hairline scratches).
Here is one that sold from a 2015 with new tires, $600 OBO.

Here is another one, that is factory 22" RT off a new 17'. Originally asking almost $2,250 back in April. He finally just sold them for $1,000. No one was willing to pay full price, when they could purchase replica's or a different set for cheaper.

Anyways, the OP can sell them for whatever price he would wishes. I was just providing him prices based on what I have seen here and I am sure others are doing the same.
