Malaysia Bunga Raya Series 2005 10 Cents Struck On 1 Cent Planchet
Wrong planchet and off-metal errors occur when a correctly made blank from one denomination is accidentaly fed into a press for another denomination.
When a planchet is struck by a pair of dies that do not correspond to the denomination intended for the planchet, a wrong planchet error occurs. For example a 2005 Malaysia Bunga Raya Series  10 Cents coin struck on a cent planchet will have the same weight and copper composition as a cent. It will likely be smaller than a normal 10 Cents coin, but probably slightly larger than a normal size of a cent because the 10 Cents collar die cannot restrain the smaller cent planchet from expanding.
The "Wrong Planchet" or "Wrong Metal" error frequently occurs when a tote bin fails to be emptied with all the planchets and a planchet may still remains stuck in a corner or in the groove of a tote bin door. If the bin is then used to transport planchets for a larger diameter blank or planchet, the wayward blanks, still retained in the bin may be transported to a coining operation of another denomination and struck with that denomination's details.


  1. Dear Sifu,

    I got a 2006 10 sen coin with yellowish colour between 12.00 o'clock and 3.00 a'clock just below the rim. Is it an error or just ordinary coin.

    Can you pls verify if these varieties correct. I try to check in the internet but there is no reference.

    2008 Variety 1 - Rounded Rim (Planchet a bit thinner compare to 2008 V2)
    2008 Variety 2 - Flat Top Rim
    2009 Variety 1 - Rounded Rim (Planchet a bit thinner compare to 2009 V2)
    2009 Variety 2 - Flat Top Rim
    2011 Variety 1 - Thinner Wording And Denomination
    2011 Variety 2 - Bolder Wording And Denomination

    Many thanks in advance for your help.

    best regards,

  2. Seri,
    All the varieties you listed are possible.Because due to high mintage, the Mint need to use many working dies to mint coins, sometimes different dies engravers or different suppliers of planchets will result the varieties of coins.
