What was our most expensive postage stamp?

Factual Questions
1

I think now it’s a dollar, but I’m pretty sure it used to be much higher.

There’s a 2 dollar stamp with a bobcat or some other cat on it.

Priority mail stamps are $3.20.

There were $5 stamps in the past couple of years. I think they’re still printing them.

Express mail stamps are about $10.75. (I don’t know whether or not they’re still printing the stamps.)

A few years ago, International Express mail was $14, and there was indeed $14 stamp. I don’t know what the rate is now, and if they’re still printing those, either.
