A wrong metal error is struck on a planchet intended for a denomination of a different composition. This includes a Malaysia 10 Cents cent coins struck on a One cent planchets, 20 cents on a copper planchet , and higher denominations with bigger planchet struck on smaller planchets of different metal.

A second type is the wrong planchet error, defined as a coin struck on a planchet of the correct composition, but the wrong denomination. These include Malaysia 10 cents coin struck on a 5 cents  planchets, 20 cents struck on a 10 cents planchets, and 50 cents struck on a 20 cents planchets.

A third type is the wrong planchet stock error. It occurs when clad coinage strip rolled to the thickness of one denomination is fed into the blanking press of another denomination; the diameter is correct, but the thickness is thicker or thinner than normal.

A fourth, rarer form is the double denomination. It occurs when a coin is struck on previously struck coin, such as 20 cents struck over a 10 cents coin. Since our Shah Alam Royal  Mint has struck coins for foreign governments in the past, it has been possible to find in circulation Malaysia coins struck on planchets intended for foreign coins, as well as Malaysia coins struck on previously struck foreign coins.

Another rare type of wrong metal error is called the transitional error. It occurs as the composition of a coin changes. Some Malaysia Parliament series of 1976 one cent coins are known to be struck on copper planchets of 1973 composition, while some 1973 coins were struck on clad planchets (1973 one cent coins were struck with planchets for both types of coins available side by side).

Some errors collectors claim that wrong metal and wrong planchet errors are striking errors, not planchet errors. Their argument is the planchet is OK,it was just fed into the wrong coining press.

One fact true for all errors of this broad category is that the planchets must be of an equal size or smaller than the intended planchet. A 20 cents planchet, for example, would not fit between the dies of the smaller 10 cents.


  1. Those are really rare typed error coins!

  2. Hi Dickson,
    Phiit, nice collection.
    By the way, is the 3rd coin from left on the upper row, ie. a 20sen on a bigger planchet in the 1st picture an assisted error?
    All in all, very desirable error coins.
    Thanks a lot for sharing, Dickson :)

  6. hi Dickson,

    I saw a piece of 20 cents (2005) struck on a copper planchet.
    The seller intended to sell it.
    Hence I'd like to enquire how much does it worth since it is a wrong metal error :)
    By the way, the coin is of lustre appearance.
    Thanks a lot

  7. Dear Anonymous,
    If the coin is of lustre appearance,I may pay RM380 to RM450.

  8. Dear Dickson,

    Wow, didnt know this wrong metal error coin carried such high market price.
    But I was wondering how this could happen. Is it because of the worker in mint factory struck it for fun or is it caused by the technical error similar to 1 cent coin 1976 or 1979?
    How many of wrong metal error 20 cents coin in the market?
    If its the technical error, would you foresee that this wrong metal error future market price will exhibit like the 1 cent coin 1976 and 1979?
    Appreciate your reply and thanks in advance.

  9. Hi Anonymous,
    All that you mentioned are possible to happen.Likely it was a case of mixed planchets in the tote bin!
    These are scarce errors and in due time,it is possible for thier market price will exhibit like the 1 cent coin 1976 and 1979.Depend on the demand!
