In 1983 Bermuda issued a dollar coin and a 5 dollar coin. Both were in nickel-brass. Curiously, the dollar looks very similar in shape, size, colour and thickness to the UK pound coin, which was also released that year - or perhaps not so curiously, since the Royal Mint produced both coins.
The dollar showed a cahow, and an onion was featured on the 5 dollar coin. These coins were issued again in 1986 only, then they were demonetised in 1990. I am curious to know whether the 5 dollar coin ever circulated.
