Irish Ballykinlar Internment Camp Tokens 1919-1921 should be added

The Ballykinlar Internment Camp Tokens, produced in 1921 at Ballykinlar camp in what is now Northern Ireland should be considered for addition to (probably) this page: https://en.numista.com/catalogue/index.php?ct=exonumia&ttin=y&p=1#e_irlande

The Ballykinlar Internment Camp Tokens are circular and made of card in various denominations, and were referred to as 'coins'.

Although rare, they are occasionally offered in auctions and at shows.

Internment Camp Tokens should be listed in the main catalogue - considering that there are German ones listed in the Notgeld section.

The Ballykinlar ones should be classed as both an Internment Camp issue & a local currency - & because they were printed on cardboard, I regard them as notes rather than coins.
