Registering for the £100 buy-price

Since 2009 the market value of the undated 20p has doubled from £50 to £100. The London Mint Office would like to buy these undated 20p coins for their customers and so we are offering the public a quick and easy way to benefit.

Not every 20p is affected so it's a case of hunting out the rarities.

To claim the £100 buy price you need to register with The London Mint Office before sending in the coin. Our initial allocation of registration places is already gone but we have released a further 10,000 places so you should register as soon as possible. You may use the form at right to do so.

Registration is free and we will email you details of how to download the official Undated 20p claim form which will include details on how to easily identify the undated 20p coin and how to despatch it to claim the purchase price. It also includes other materials including a money-off voucher, which all registrants are entitled to regardless of whether or not they find an undated 20p.

You are under no obligation to sell the coin should you find one, but once you are registered, you have the option of accepting The London Mint's £100 buy price.

Do not delay. The initial allotment of places are already allocated - a further 10,000 places have been released but these may not last long. You should register even if you haven't yet found an undated 20p, just to ensure you can benefit from this offer.

Since 2009 the value of the Undated 20p has doubled form £50 to £100
