O’Brien Rare Coin Review: Why is the 1943 Irish Florin so valuable?


The 1943 florin is the rarest ‘modern’ Irish coin to have actually circulated.

Both of the coins listed above were minted for only testing purposes, i.e. to calibrate vending machines and they were supposed to have been returned by the P&T engineers that used them.  For some strange reason, a few seem to have been misplaced and didn’t make it back to the depot.

With the price of silver bullion rising and WW2 approaching its darkest moments for the Allies, neutral Ireland decided that 1943 would be the final year for its 75% silver coinage.  No 1943 shilling was minted and only a limited supply of the 1943 florins and halfcrowns were  struck by the Royal Mint in London.  Bullion silver prices kept on rising and, by 1946, the last British silver florins (50% silver) were minted.  From 1947 onwards, circulating British coins contained no silver.

  • It is generally thought that just one bag of 1,000 Irish silver florins were transported to Dublin in 1943
  • This one bag of 1943 florins had a face value of £100

How many 1943 Irish florins exist?

Irish numismatic researchers believe between forty and fifty 1943 florins are now available to collectors from those taken from that one bag of coins.  The remainder of these 1943 florins + any previous silver florins on hand, were subsequently ordered to be returned to the Royal Mint to be melted.

  • 4 are known to be in ‘uncirculated’ condition (MS-60 to MS-65)
  • 4 are considered to be in ‘extremely fine’ condition (XF-40 to XF-45)
    • one of these is alleged to have been damaged by a screwdriver (so, there is only 3 in this grade)
  • All of the others have been ‘circulated’ and usually range from Fine (F-12 to F-15) to Very Fine (VF-20 to VF-35)

To the inexperienced coin collector, this means that the rest of the coins have been used for the purchase of goods or services, and this constant ‘handling’ causes ‘wear and tear’ on the coins – resulting in loss of design detail.

One of the things I have learned over the past 40 years of coin collecting and dealing is the following :-

  • The buyer always under-grades the coins they are thinking about purchasing
  • The owner always over-grades their coins – so as to maximise the perceived value
  • The reputable coin dealer usually grades somewhere in between the two above

I am constantly asked how they are worth and, since I do not have one in stock, my opinion is moot.  Several examples have recently been sold at auction and the prices are there for all to see, therefore (contrary to popular opinion) these coins are worth whatever you get for them on the day !

  1. I have some of these coins swear like 5 i picked up some coins from this chick the other day for 15$ came with 165 coins and i seen like 5 of these coins your talking about ima check the years now


  2. I have one of these 1943 florin coins!!! It was given to me but it has a small hole in it to wear it as a necklace. I wear it as a good luck charm not sure if it’s still worth anything because of the hole.


    • It is worth something.

      Yes, the ‘hole’ and the ‘constant polishing’ over the years will have reduced its price but I doubt if it will go for less than a thousand Euro at auction. Remember, it is one of the rarest circulating coins of the modern series and there’s only about 50-60 of them out there… and now we know about your 1943 florin.
