Color hard to say due to monitors and how they affect color. I went to a couple of different computers with different monitors and after great scientific research I will agree and change my color to Red Lilac and thus a Scott #70. Its either a #70 or #70c.
Condition of the stamp is bad, I wouldn't buy. Top and bottom perfs are cut, stamp looks to be in pretty bad shape. Probably a placement holder until the collector could find a better one.
I buy a lot of stamps off
ebay and I do think if you put it up for sale, you'd most likely get $10-20. Probably more on the $10 side.
