I picked these up from the lady with the street stall yesterday. I've ruled the cross out. Not silver. Tiffany made some very similar ones but think it would have been marked Tiffany co if it was. I can't find anything resembling the coin/pendant. As for the brooch, not sure if it is vintage or modem reproduction. The metal seems very malleable and bendy.
Good morning Debora. I was thinking more of this sort of thing. Thanks for reply https://www.ebay.com/itm/134586965536
Certainly an arresting design and one I wasn't familiar with. Thank you. Off topic... That's a pretty funky Tiffany logo. I'd be more comfortable with the cross on offer from 1st Dibs. https://www.1stdibs.com/jewelry/mor...tiffany-co-sterling-gold-cross/id-j_10924892/ Debora
The little medallion is Japanese, depicting Emperor Jimmu, legendary first emperor of Japan. He was assisted in his battles by a mythical crow, the Yatagarasu, depicted perched on top of his bow. (google translation) The character under the "of" was translated separately as "foundation" - perhaps related to National Foundation Day (February 11), a celebration of the founding of the Japanese state. https://en.wikipedia.org/wiki/Emperor_Jimmu https://en.wikipedia.org/wiki/Yatagarasu
Here is a somewhat similar one, described as a census badge: https://www.ebay.com/itm/1445405038...MI3fr0udTe_wIVmUl_AB375AOBEAQYBSABEgI7FvD_BwE
