In today's world, everything that’s old can be described as antiques and generally speaking that’s quite true. A product is considered to be an antique if it is over a hundred years old or is rare enough to have some value. In other words, these are old items that are in limited supply.An antique is something collectible. It may be a piece of antique furniture that you want to collect to enhance the look of a room, or a piece of antique pottery to decorate a corner cupboard, or some antique book.
