1955 British Carribean Territiry eastern group 1/2Cent [solved]

This coin looks too have tabs on the sides from the original press. Never seen this before

 Once part of a bracelet. 

 Rather than drill a hole each side then add a link inbetween 

 like that, which I own, the coin stays intact and instead the loop is 

welded/soldered on the outside. 

 A quick picture, with flexible not solid links … 

 Just three coins, from maybe 10 altogether, as an example. 

That would be for a bracelet, whereas it could have been a 

necklace with just that one coin, and then a separate chain.
