Here's an interesting auction......

Are these rare and collectable? Interesting enough, I found a store of these things.

Does anyone here know?

They are rarely rare, and although there are many people that collect them, the resale value on them is usually pennies on the dollar. But they are nice to look at.

I have a lot of First Day covers, but I don't own any with coins included

I was reading further into the website and found a 1938 card with a $577 price tag on it.
