In the early 19th Century,
The Royal Mint produced very few crowns, because they took two blows on the presses, & the moneyers (who were paid by the piece) didn't want anything to do with them. It was remarked at the time that this was very unfortunate, because of the considerable demand for large silver pieces such as the French five-francs & Mexican dollar.
And the production of big silver pieces for circulation continued, in some parts of the world, even through the period of the First World War. So some people must have found them more convenient than otherwise. I know my five bolivares (Venezuela) & sol (Peru) pieces, among others, show plenty of circulation wear, so they can't have just sat in bank vaults.
I'm kind of a fiend for crowns, though. In addition to the Australian of 1937, I have New Zealand of 1947, with the fern design (not the Waitangi, alas) ; the Bermuda of 1959, & the undersized one of 1964 ; the British "rocking horse" of 1935 ; the South African springbok & ship (1953) types ; the Southern Rhodesia 1953 ; & the Ceylon 5 rupees of 1957, which is a crown in all but name. I'm sure many people have better collections, of course, but those are mine. And the Cyprus 45 piastres is high on my wish list...
