antique tin patty pan molds, rustic rusty metal heart shaped pans made in England

Lot of 10 rusty old heart shaped pans, stamped England. These are probably early 20th century vintage, I think? They're quite heavy, thicker steel than the mid-century pans I've seen.

Size is 3 1/4" x 3 1/4" x 1 1/2" deep. These look to me as though they're too rough for use as cookware, but they'd make wonderful primitive hearts for Valentine or wedding decorations.
