Nice e-trac find this morning, over 12" down in unploughed pasture, lovely signal. These tokens were produced for use in the colonies and can be quite rare and valuable. I've stuck it straight on E-bay!
If you like it, you might want to rethink selling because it will not be a big payday. These don't really go for a whole lot more than just a regular shilling would. I have 4 friends who have dug the 18 pence, and I found an 1812 3 Shilling. Cool finds, but not a lot of value.
