That sure is a sweet 'Hard Times Token with great detail & patina.
I call those things you asked about 'Rivets' but likely the wrong term , held leather pieces together, tuff to put a circa date on but yours looks old.
Your 1266-X has a different loop than mine but I find in the Woods , Grass, Corn Stubble ? the Heavy loop 'Bull dozes' the brush easier than the light coil's (like on my G2+), I feel like i'm gonna break the Coil just hitting a sapling.
A neat bunch of finds you got there.
