I'm pretty sure on this teaspoon, but not 100%. The hallmarks are a bit faded, but I think the marks are King George IV, S date code of 1833, Leopard head without crown, and Lion. If these are correct, that makes this sterling from London, 1833.

I do not see a maker's mark and there is a curious "PATENT 1859" clearly stamped on the reverse. I'm not sure on pattern -- Olive?

I will post a few photos.

Thanks.

this might be American coin silver - mark looks like that of Philo B. Gilbert and/or associated mfgs. I recently bought some spoons with the same mark (different design).

This is an American pseudo-mark and definitely not a British hallmark. Close examination of the "hallmark" will show inconsistencies with the real thing and the use of "PATENT" is a clear pointer to a US origin.
