Our rivets from the bunkhouse site are brass or an alloy like yours and we 
did have one with a star.

But, hmmm.  Our [what I called] spacers [and you called] washers (at our 
cowboy bunkhouse) are dead grey with no hint of copper.  I forgot to say we 
have nails driven through some of these lead items, we found them in the 
dirt like that.

We've had the cuprous washer like items at other sites (when they're cuprous 
I call 'em "burrs") but they're always flat with no sign of the V shape like 
these artifacts depicted by John.
