British Celtic coinage

I was in the British museum last week and there is an exposition of the celts.
There were a lot of coins on display and I was hoping to know more about them so I searched them in the Numista Catalog, but I do not find them.

example:

British Celtic coinage
Coin of the Trinovantesminted at Camulodunon.
The Trinovantian tribal oppidumof Camulodunon (modern Colchester) was minting large numbers of coins in the First centuries BC and AD, which have been found across Southern Britain.
Common motifs on the Camulodunon coins included horses and wheat/barley sheafs,
with the names of the rulers written mostly in Latin script, and more rarely in Greek.

I searched in "ancient rome" and in "gaul" but i did not find them,

Can someone point them out?

Try there: https://en.numista.com/catalogue/england-1.html

If not there, I believe they are not in Numista catalogue.

Some old Scotland and Ireland is there also: https://en.numista.com/catalogue/irlande-1.html#devise406
https://en.numista.com/catalogue/scotland-1.html

But I believe that is not what you search for.

Seems these coins are from Celtic Britain, before or close to the Roman invasion, right?

You last chance may be Roman provinces, but if not found... maybe this country is still not listed here yet.

Thanks for the input
Roman provinces is indeed the best bet (apart from "gaul"), but I see only coins linked to the romans, The celtic coins seem to be made independent fron the romans

Gaul does only have coins from the continent

And I was expecting to split Hispania coinage from Gaul that way... If not the name of Gaul would be useless, considering celtic tribes all together.

I think I'll create the Celtic Britain country. I've found on an authorized website pics of a 1st tribe in Celtic Britain. You'll be welcome to create a file about the coin you cited if you've enough data to share with us.

Hi,
I know i's not a Numista catalogue thing, but have a look for these books, they might help. British Celtic are pretty awkward as new coins and variants seem to turn up every five minutes. The first book was a catalogue to date (1996) of the Celtic Coinage Collection of the British Museum.

Just by way of an update to this thread, I am pleased to confirm that a new 'country' entitled Celtic Britain has indeed been created and currently lists 80 examples out of a total of 450 different types shown in the 2017 edition of Spink.
