 The coins were slowly withdrawn from circulation, before finally being demonetised (no longer legal tender) on 1 May 1990.After the withdrawal of these coins, cash transactions were normally rounded to the nearest 5 cents, a process known as Swedish rounding.Some larger retailers (notably one supermarket chain), in the interests of public relations, elected to round the total price down (so that $4.99 became $4.95 instead of $5.00).
