Hi everyone, happy weekends and Merry Christmas to those who celebrates it.

My latest catch on error coin, which dug a considerable big hole in my tiny student pocket is this Wrong Planchet Error coin.

This is a wrong planchet error coin which the 20 sen dies were used to struck a planchet of 10 sen.

The size and weight of this specimen is exactly the same as the normal 10 sen planchet. The measurement that I took on this coin showed that this specimen is thinner than usual 10 sen coin. This is probably due to nonexistence of the rims. And one more perhaps the pressure used by 20 sen dies were higher than 10 sen dies set, hence makes the coin thinner than usual.

On how to differentiate between a genuine wrong planchet error and a fake one, we can analyse the legends near the rim area. Due to the nonexistence of the collar die set which is supposedly to hold the edge, the legends near the rim will exhibit a fishtailing characteristics. This fishtailing occurs due to no normal force from the collar die, thus a solid legends failed to be formed.

In this specimen, fishtailing is obvious on legend "BANK NEGARA MALAYSIA" especially on the N of NEGARA.

Salam Mnfaj,
Wrong planchet error memang ada dikaitkan dgn "error palsu" dan tidak begitu sukar utk membuatnya.
Depankanta belum berpengalaman melihat sendiri syiling begini tentu sukar menentukan mana error ori dan mana error"buatan".
Depankanta berpendapat tempat yg perlu diberi perhatian adalah hujung arah rim semua huruf perlu dilihat bawah kanta berkuasa tinggi @ microscope bagi melihat adakah ianya kesan tempaan atau terdapat kesan repair selepas dikikis.Ada juga pendapat yg menyatakan fishtailing juga boleh dibuat.
Semoga syiling yg ada ditangan mnfaj ini dapat dijadikan bahankaji bagi pengetahuan kita bersama tentang kategori error ini.Ini juga akan memantapkan lagi kepakaran mnfaj dalam syiling error(nanti depankanta pun boleh tumpang.hehe)
Terima kasih banyak2 mnfaj...
