Looked Like An Errors But It Is Not !

I found this Malaysia Bunga Raya series 2009 20 cents coin from a batch of coins collected by my niece,Sia Zhiau Zhuin. On first glance, it really exhibited a very unique errors that I cannot explain how it was happened.

It took me a couple of days trying very hard to figure out how it was formed. It just cannot be explained with normal minting process.

Not until I recalled a collector who showed me a piece of one cent coin with similar error many months ago. I got him an explanation for his one cent coin which he had paid with quite a hefty some of money.

It was an "error" formed by glue stuck in between two coins. When the glue became dried and solidified, then you separated them, a mirror image of a coin was formed on the glue.

The "error" looked very unique, like it was struck with a fragment of metal stuck on the coin but the weight is   same with a normal 20 cents coin.
The "error" can be peel off !
Be more careful and vigilance when you buy an error coin.


  1. Hi Dickson,
    Thanks for the useful information.
    We too encountered sort of the same phenomena before but the 'errored patch' didn't resemble anything familiar except like extra metal.
    These hardened glue can be quite misleading or rather quite convincing esp like your example here.
    Will definitely keep this in our mind.
    Very nice and useful article for all error collectors.
    Thanks a lot, Dickson :)

  2. Hi Mr Dickson,
    Bukan semua jenis glue dapat buat "error"macam ini.Perlu juga kita tahu adakah syiling ini terkena glue dalam atau luar kilang,kalau dalam kilang untuk apa glue ini digunakan?.Soalan ini timbul kerana kelihatan glue yg dijumpai adalah hampir sama jenisnya.
    Terima kasih banyak2 Mr Dickson,simpan elok2 syiling ini kerana kalau nak buat memang tak jadi cantik macam ini....

  3. Whycollect,
    It took me a while to figure out its 'errors'!
    Understand the process of minting is still very essential for an error coins collectors.However, our Kilang Wang BNM is still closed for public.

  4. Hi Depankanta,
    "Errors" ini memang cantik dan saya hampir terpedaya olehnya!

    Saya pasti akan simpan baik-baik untuk sebagai bahan rujukan untuk collector baru!
