The florin was known as 2 Bob as any native speaker over 50 will recall when simpler terms were introduced to aid the less educated and those with a paltry 10 digits or a deficit in the book leaning gazebo.
A two-shilling piece known as a florin (an early attempt at decimalisation, being £1⁄10), was in everyday use. It was referred to as "two bob", a "two-shilling bit", or a "two-bob bit". A two-shillings-and-sixpence piece, in use until the introduction of decimal currency, was known as "half a crown" or a "half crown".
Interestingly the 1/8 of a quid or 1.25 florins , two bob nad a tanner was often called by the wartime generation
"arf a dollar" as sterling was in that balmy age worth nearer 4 to the greenback unlike today's 1.25
I wont confuse you two thousand guineas connected to horse , a pony related to wagers or a monkey until we ay have a rabbit on the dog, jus t rmember 2 bob's not enough for Socal
Your fluency is admirable for an alien and one lacking an Irish education, the folks who taught the English prose and poetry from Sheridan, Dean Swift Yeats, Tom, Friel, O'Casey ,Paulin, Geoge Bernard manning, JAYZEE Kavanagh, Shaw Dunleavy , but don't get Wilde, it's the attempt like the tobacco that counts.
As an easy primer pre Fiinnegan's Wake or You'll eases remember the vas deferens between a girder and a joist in a Dublin accent
An Irish tried a scribble in French won the Nobel Prize for literature, poet's 10 a penny in Portpartrick.
Asa kid I had a 1/13th of a shilling coin from Jersey I kid you not.
