The important things to retain information when looking for one of the new undated 20p coins are the true value of the currency. There are some sellers register the 20p coins for up to £1,000,000 (yes, one MILLION pounds!). The bumpy value of these coins is hard to say at the same time as it is whatever the market will stand. At present £50 is offered for each undated 20p coin by the Royal Mint though it is true to say that they will no doubt sell them back to the public at a higher price than this. However, it is worth nowhere by some of the prices some sellers are trying to achieve simply because such a large number entered the public ground. The undated 20p coins will have a good chance of increasing in value over time possibly but it will be a slow and long process and is not likely to ever be worth the sort of facts some sellers are trying to find.
To put it into background, back in 1983 the Royal Mint made a mistake with 20p coins by putting "new pence" on the currency. Yet, decades later this coin has only increased in value to a couple of hundred pounds and it is also worth noting that much less of these entered circulations. Undated 20p coins are appeal what it is worth to you personally. If you are a collector then it may be worth slightly more to you out of personal interest but if you are looking at it as an investment then the undated 20p coins are probably not the best option for you and it is certainly worth making sure you are not paying stupid overstated prices for it.
As a result, if you're looking for undated 20p coins as an investment or to add to your collection then check you are buying from a genuine seller, read all the small publish, only deal with sellers that will use recorded delivery and most importantly check that the 20p piece that they are selling has no date on both the front and back of the coin. If you want a more stable solid investment in coins then of course try looking at habitual gold coins. These coins have an established value and can often be cheaper than the so-called no date 20p coins and keep on to rise in worth.
The problem with the true value of the undated 20p coins are “nobody really knows what it is worth”. The price is probably being inflated short term by buyers who have heard about it on the news and tried to get in to earn immediate cash. However, when the worth has settled this could mean demand and therefore price settled. Suddenly falls and is worth less than you possibly rewarded.
