Welcome to numista, Welcome to 2024.

Please read the forum policy before posting.

Please give the numista link to the coin in question and explain “double barred”, please? Where on the coin and then give us a close up of it, please.

Impossible to see anything on your images…..

Here is documentation of the 1979 and 1980 coins:

I can find no reference to a double bar variety for 1984.  Using Ole's graphic and your coin picture it's obvious that yours is not a double bar variety.

N#904

Your 1984 50 cent is not Double Barred. Just a bog standard 50 cent coin.
