Any Stamp Collectors Here?

I found 2 stamp books & inside one was a envelope with glassine envelopes inside it - and inside one of the glassine envelopes were all these George Washington 2 cent red stamps. Googling Washington 2 cent red stamp turned up stamps selling from $2 to $2,000!
How do you tell the difference in 2 cent stamps? (I notice the first 2 have wheat stalks around portrait instead of words + 1 is a dark red - are they the expensive versions?
What is (and how do you tell) a carmine 2 cent stamp?
Thanks; any help would be greatly appreciated.

 

I am a stamp collector and this is my 2 cents.
there are so much design variations and types in these kind of stamps and you are better off in a regular stamp community forum.
I would advise you to pick up a Scott Catalog of US stamps and (a nice lens or scanner or digital microscope) and figure out what exactly you have.
One good site is the swedish tiger.

best of luck
