Found this at the bottom of a box of silverplate. I got a good close up of the Pat Date. I am serious. It really looks like 1823. I know better because Whiting did not start to produce sterling til 1866.
Someone tell me the pattern and intro date. That should clear this all up.
It is a chattered mark, meaning the hammer bounced or it was double stamped to get more depth with the punch misaligned. Yours is a misaligned triple stamping of 1920. Regards, Tom
