Craigslist ad for a garage sale in my area...doesn't mention coins in the verbiage, so maybe I have a chance...
I'd have gone to see what was in the wooden glass topped case, and possibly buy that whole thing - depending on what kind of dollar figure they would throw at you.
Actually didn't see the toilet seat after I got there, but one of the cases was "ancient" coins he said came out of the ocean...nothing much identifiable there. The other had some goodies I bought And I just had to dip the pesos (it's a sickness...)
