To Coin A Word

The words “to coin” can be used as a verb with a literal meaning to mint a coin, but in 14th century Europe, the term “coining” was associated with inventing words. By the late 16th century, “coining a phrase” implied the invention of a series of words used to complete a sentence. There's also a Greek word koinē, meaning "common" or "shared".  It is used for common language or lingua franca used by speakers of different original dialects or languages. The New Testament was originally written in Koinē Greek, which was the common language, accessible to all, rather than the formal Classical Greek.
I love discovering the history of words, how and when they were first coined, and how their meaning has changed down the centuries. In the study, we have a little paper cup. It is full of the odd coins we find in pockets and bags at the end of the day, or when we are tidying up the table...

What do you call such a collection?

Is it small change? Or loose change? 
I remember that when we had that huge mortgage, I used to say "We do not have loose change here, only tight budgets"

Have you come across the word

shrapnel?

I was thinking about this, and wondered who coined this term. It is an eponym, for Henry Shrapnel [1761-1842] who invented an artillery shell filled with lead musket balls, and a bursting charge, so it exploded in mid air.

The debris from exploding shells and bombs generally was called shrapnel. In WW1, metal and paper shortages meant they had problems at the Monnaie de Paris [the French Mint] and made cheap coins, and there were locally produced banknotes on cheap paper called billets de necessité. Troops fighting in France referred to the tattered notes as shrapnel - . By WW2, shrapnel  had become the slang term among the forces for any small coins. However it was not recognised in British dictionaries till 1984. 

Bob and I were talking about this - I first remember coming across the term in the 90s when I met my friend John [ex Forces] 

Whatever you call such a pot of dosh**,  it is useful to have some around, for charity pots, car park machines, and grandchildren who would like to buy their own treats. Many older people, and people managing debt issues, prefer to pay with real cash they can manage, rather than the credit card, which is 'virtual' money and sometimes hard to keep track of.

I for one do not want a cashless society, for lots of reasons.
What do you call shrapnel?

Are you happy to go 100% cashless?

 [they can't agree on the origin of dosh- it may be doss, the price of a bed for the night, dash, the Colonial African word for a bribe, or the Russian-Jewish word dosh meaning nose, as in pay-on-the-nose, i.e. pay in cash]
