This thing looks bassackwards to me. It would seem the larger
coin slots would be closer to center and the smaller slots
towards the outer edge. I see it with my own eyes but still
don't see how it works as advertised.
I don't own one of these but if I did I would take it to a local coin shop and
test it with some of their coins. I'm sure that the slots closer to the middle
for gold and the outer slots are for silver.
After a little more research, very little, it turns out that
gold is nearly twice as heavy as silver. I always knew it was
more dense but I never realized there was that much difference.
Knowing that I can see where some of the larger slots that are
closer to the center were for silver and the heavier/smaller
gold coins were weighed in the outer slots.

3031) I've never seen a sheet metal caltrops before, but that is
obviously what it is. (Something initially to halt mounted
military charges.) These would probably do a nice job of
slicing open tires.
3032) At a guess, something to plug into a removable plate (e.g an
access plate for shutoff valves), turn to lock the handle to the
plate, and lift it out.
3033) Assuming that what is behind it is a mirror reflection, I see
what appears to be a Type-N RF connector, which suggests that
this is either a delay line, or a quarter-wavelength or
half-wavelength stub for something like an antenna.
3034) Hmm ... no size on this. If the notches for the pipes formed
a horizontal line, I would suggest that this is part of a
cattleguard (placed in a recess in a gateway. Cattle won't
cross it, but a vehicle can drive right over it.
But -- since they are forming a slightly concave shape, I think
that it perhaps forms a bench for outdoors use. Pipes go in the
notches, and the base fastens to a flat surface. Looks like a
few too many mounting holes compared to what I think that it
3035) Looks too thin to be an adjustable height support for shelves,
so I don't really know.
3036) Again -- no size. And slotted head screws are made in all
kinds of sizes.
But the grounding cable terminal looks fairly large -- say at
least for 1-0 wire. And it looks as though the terminal has
been soldered to the spike, which suggests that it is probably
So, I'm going to say that this is intended to attract lightning
away from other adjacent things, and to ground it. Certainly
not the shape of the already ancient lighting rods which I knew
in South Texas back in the 1950s, but the shape should suffice
for the purpose, and those screws allow the spike to be replaced
if it gets partially melted by a heavy strike.
Now to post and then see what others have suggested.

to drive over a couple of these on airport runway.
