The differences between bullion florins and fifties can be summarised here:
.925 for all florins up to 1945. The earlier 2 monarchs are typically cull coins or slicks like the one pictured earlier in the thread. They were heavily circulated and it shows.
The most recent pre46 monarch series is typically in gradeable condition, tending to aUNC and sometimes UNC for the last year or two of mintage. Huge amounts were minted so that US and other military personnel stationed in Australia had currency, from what I’ve read
These latter coins are typically in better grades as they were less circulated before the debasement from .925 to .5 in 1946
With fifties you have a single year and the only real hope for a numi is the rare double bar or if you bought UNC (available a decade ago in quantity, I don’t know now)
With .925 florins there is a good chance of picking out a few rare coins eg 1914 Heaton but the odds are very high the coin will be in the lowest grades
Even still, the odds are high to near certain of numismatic grade coins in the 1942-1944 range...a small premium but one nonetheless (although if buying from a
On SS popularity waxes and wanes. There have been many times you could not give away post46 and the odd time large amounts of fifties went unbought even when 7.50 AUD
You rarely see .925 in bulk here...yet
What I suspect is coming soon is a lot of hoardings come to market in the run up to 50 AUD. You’d think that will put a ceiling on prices for a time until inventory is exhausted or the spot price runs harder. The reason is that figure would be tempting to an old time stacker from the last run up. I see in the trading section already one or two vendors recently seeking to offload quantities of bars and coin at the current price. Around 10x that might put $1 million of product into the supply side here and I don’t know if there is demand to absorb it
