I suspected, am routinely skunked but thought maybe silver when I saw it.
Paid $5.00 at a junk store but haggled for a pair of artic cold weather socks be included. Jeweler I took it to believes its an old pour from turn of the century in around .700 + sterling. Its real but we can't figure out the 3132 marking as its backwards? No matter its 70% and I consider this a excellent score. We couldn't agree what it was intended for?
Weight 16.84 ounces, troy weight approx 70% of that. Enjoy.
