I recently had a customer come in to sell their scrap metal and sold
off a small hand-forged bowl with a spout. They said that it was
platinum and the shop manager bought it at scrap value as he cannot
figure out what else it could be. It is not stamped with the typical
marks; it has 505 on it and also, APW, with the letters sort of
combined. The man said that his father worked for the Manhattan
Project and it was used as a crucible for engineering a bomb. Anyway,
I was interested in buying the bowl for scrap value from the store
because I think that it is worth more than scrap and is (maybe) a
piece of history. Any idea what these stamps could mean? I cannot
find anything with a google search. Also, I have a tiny amount of
doubt that is is actually platinum. It has a small amount of memory
to it when you flex the paper-thin rim, which seems unlike platinum.
However given a little bit more pressure, it bends and stays. It is
heavy for its size (32 dwt)and the size of a large orange. It heats
up white hot without melting, does not discolor or tarnish (like
PD),files just like PT, and does not react to acid tests. When tested
with the GT-4000, it tests in a range higher than 18k, but not into
the Plat category. Anyone have any idea if this actually
characteristic of PT and what those stamps might mean?
Thanks in advance!
