They are "toy coins", intended for either cheap jewellery or for play money - whatever the purchaser wished to do with them.
The design is very loosely based on the American
quarter-eagle and
half eagle gold coins, except of course that the design is in regular relief, rather than incuse. And other design differences, of course, such as the lack of a denomination.
As I've said when similar pieces have been posted, the use of the English word "Germany", rather than the German word "Deutschland", indicates these pieces were made for export to an English-speaking country. "1923" might be the actual date of manufacture, or it might be completely fictitious.
The piece with the "odd script" is interesting; as far as I can tell, it is not an actual foreign language but either meaningless gibberish or perhaps a Masonic-style cipher. I suspect it was issued after the first one, with the manufacturer of the first piece being asked very nicely not to put "United States of America" on their toy coins anymore.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
