https://www.icloud.com/photos/#03fZPcOfOJv6v8dR4FWaEAOgA You can view the library here. Some of these that I googled have ranged in value from $200 - 400k USD so i'm not sure exactly what I have here but looking to entertain any offers or guidance on how to get these graded. I mean this niagra falls one postcard w/ this ben franklin stamp has to be worth something. Title is just to grab attention I did however find some of these stamps I have go for 250-400k and they look the damn same to me.

You might get better responses on specialized forums for stamp collecting. (e.g. https://www.stampcommunity.org/)

Unfortunately, I haven't got experience with US stamps, there are a lot of factors for evaluating stamps:
colour grade
colour variant
size
misprint
..

Thanks for the input i knew it was a longshot but was really hoping too find someone who collected these suckers as well as bitcoins

as correctly stated by @Iced the value of the stamps is given by a whole set of factors.
To determine these factors first of all take "single" photos and not in groups.
Secondly, this is not a huge collection and no it's not worth millions of usd.
a bit like what happens to me when they ask me for my opinion on a collection it is good to be very clear right away

I don't know which ones you have seen that have these ratings (400K USD :O ) but unless they are "misprints" or particular runs, the ones you have shown are very common.
For example, I see many examples of 1c Benjamin Franklin, Scott n. 300 issued in 1902 (photo 1-2-3-7-8-9-14-15) from the catalog is 0.50 usd (perhaps on postcard or envelope support it can reach 2 USD).
it's enough harder finding a buyer some times because these are really commons (and not in "perfect conditions" like photo 9)
Maybe you can have some rare use for cancellation/destination but its.... rare.
