The coins commonly encountered in circulation have face values of 10¢, 20¢ 50¢, $1, $2, $5, $10, $20. The 5¢ coin is rarely seen due to its low value, thus prices rounded to the nearest 10¢. Some commodities are priced in multiples of 10¢, but stores may choose to round the total prices to 50¢. There is also a trend for supermarkets to ask customers to round up the total to the nearest 50¢ or 1 peso to automatically donate the difference to charities. The $50, and $100 coins are rarely seen in circulation due to the wide use of the lighter banknotes of the same denominations as well as their metal value.
