Those are interesting. The colors seem off. I don"t collect this series. Mainly because I would only buy them Slabbed.
I'm afraid that I have to agree with @Treashunt the color seems really off. I hope that it is just your pics and you didn't get taken on them.
After looking at the pictures, I knew you were going to get a lot of responses you don't like. There's crud in the hard to reach (when cleaning) spots of the last reverse pic. And others tells throughout.
They've all been cleaned and look unnatural, but the toning COULD be naturally occuring... but if so, it happened post cleaning. I'd say they're "worth" several dollars each, but if you like them, that's all that's important.
The color on these is not natural. They have been messed with. I still like the 1907. It's still pretty to me.
Get a feel for them here: http://www.pcgs.com/photograde/#/Indian/Grades. I'll say VF-EF. They're cleaned and won't grade. Having said that, I wouldn't be spending them, either.
