Some items are cool even if they don't have much value.

3. That might work on the RR and Steam ship co.

I'm afraid someone might wish to enhance a plain lock or key with the stamp. They could also do that with an item with an 1873 patent date. I have one that is just a plain "U.S" stamp. Looks a lot like the stamp on army guns. The U.S. stamp on an early Colt pistol or Springfield rifle could double the price of it, making it an army issued weapon. Of course they could ruin an item trying to get it right. Makes me think I'd rather sell them all, 21 of them, to a person that collects die stamps. I put one in my showcase and will see how that one goes.

In the first post I meant to say late 1800s, not 1900s
