The incuse-eagle-on-arrows design is coped from the gold
half-eagle and
quarter-eagle coins of 1908-1929. It is presumably a piece of "costume jewellery" (base-metal, not gold) intended to look gold-like by borrowing a design from a known gold coin.
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
