Two mystery items. One being a coin?

[nate7394]

All the items were found today at a house site that was gone by 1847. I found my 3rd and 4th silver coins ever with one being a 1749 Mexican 2 real coin and the other being a possible counterfeit 17X7 half real.

The mystery items...

1) A counter stamped? large cent size copper disk. There are what looks like 2 or 3 letters on the counterstamp

2) A long rectangular piece of metal with different movable parts and pins on one side

I would love to hear what you guys think these items are and how old they might be.
Thanks to all who reply!

Cool finds but I'm at a loss

Larger item seems to be part of a clock.

Flat button is a Tombac pants (usually) button.

Yeah that's what I was thinking. Must have been a huge clock!

The 1749 real is a 1 real coin minted in Mexico City.
It should be about 20mm in diameter and weigh about 3.3 grams.
It is from the series 1747 through 1758.

That button looks to be late 1700's to me
