These coins were mass produced by the Royal Mint to commemorate the marriage of the late Princess Diana to Prince Charles on 29 July 1981. The cupro-nickel coins, often in plastic cases, are worth about 50p - £1 each. Those struck in silver are currently worth around £15-£20 and are always in the plush cases.
You need to be more specific on which coins are included with the "collection". Many countries both inside and outside of the Commonwealth have released commemorative coins celebrating several Royal Weddings. Post a new question that includes the country these coins are from, the denomination, the year, anything specific about the coin (circulation-quality, proof, silver proof, gold proof, etc.) and an estimate of the coin's condition, then we can help you.
