Hi Everyone
OOPS 1st post here is the pic

I saw this #596 in my new stash of stamps and freaked out!

After running round the house a few times I took a closer look and now not sure what this is exactly. Looks like a coil, and has a Kansas City, Mo precancel. But the cancel is different than the 596 and of course if it's a coil it's not 596 either. I'm perplexed and a little bummed.

Plus it's stuck to another 1 cent stamp underneath it. I'm unsure how to seperate them of even if I should.
HELP
Nick
