Isle of Man 50p Coin from 1972 to 2017 and Sequence C under The Prefix A & B


Last Updated on:

The sequence C under the Prefix A and/or B

In this short part, it will give you some basic ideas how to interpret AC die marks on IOM 50ps. Each single dye mark not only follows a metric but also is having their own information contained. By the way, a single dye mark is only for precious alloy. It is a period of HONEYMOON between the Tynwald and the Mint that has seen from the die marks invented in 1980s. More importantly, this part only covers 50p CN coins made by the Pobjoy mint from 1972 to the end of March 2017. But sadly, they divorced in March 2017.

  • 1979 Viking boat 50p coin with AC

This AC die marks on 50p coin is the very first signal showing on Isle of Man coinage. It has a very interesting story behind it. The second theme, replica Viking boat, was entirely designed by the Pobjoy mint in 1979. The first theme was revealed in 1976. With regard to coin finish, it is better than BU but less than PF/PL.

  • 1978 IOM £1 coin with BC

This BC die marks on £1 round pound coin is the very first the sequence C shown on Isle of Man coinage. Also, this BC is the very first die marks revealed as well. The year it was 1978 and the 25th anniversary of Q. E. II Coronation.

  • 1980 Xmas 50p coin with BC

This BC die marks on 50p Xmas coin is another story to talk about. First, it is the way how do you understand the letters of BC in the Xmas series, of course, “Before Christ”. They (the Mint) intentionally used the sequence C to celebrating something, but it ended with two BC in the entire series, which are 1980 (BC) and 1981 (BC). 1981 BC can be seen below.

  • 1981 Xmas 50p coins with BC

Instead of AC, BC appeared on Xmas 50p coins in 1980 and 1981. It has two meanings of BC in 1980. One, commemorative coins on b batch coins. It tells the difference between A batch and B batch. It can be understood that they (the Mint) tried to issue two different types of coins for collectors. Two, it also can be understood the meaning of BC as Before Christ. At this point, it is very clear to say that A batch code means circulating commemorative coins, and B batch code means commemorative coins. The BC die letter were noted in 1981, in the same year, a IOM £5 coin was issued. Therefore, the sequence C under the Prefix B means a lot from the perspective of the Mint.

  • 1982 Viking boat 50p coin with AC

This AC was used in 1982, three years later after the first one in 1979, to commemorating the birth of Prince of William, King of the future. In the meanwhile, the babycrib privy (b) appeared instead of AC on proof coins. This confirms somehow the sequence C contains really important information nested. Remember AC is circulating commemorative coins, meaning currency coins on the basis of daily use.

  • 1983 T.T. 50p coin with AC
  • 1983 Xmas 50p coin with AC

This two ACs are really hard to find out especially 1983 TT (AC). Circulating commemorative die marks for this year are AA/AB/AC/AD as same as in 1979 Viking boat. Somehow, it echoes the 4-year window. Is it happened to coin-cide?

In brief, they have one thing in common above coins, really really hard to find them out. In other words, the number of mintage is relatively small. For instance, you can find out loads loads AA coins in circulation. The number of mintage is huge. Therefore, C, at this point, means that it is used to commemorate an great event. If you see AC on 50p coins which tell you that commemorate an event on circulating commemorative 50p coins (ie., AC) or/and on commemorative 50p coins (i.e., BC).
