75. Malaysia 50 Sen 1984 Third Collar Die Omitted

image 1: the coin

      My friend just found this coin in his loose change. Currently do not know what had caused this error but I am pretty sure that this is not a post mint defect (PMD) coin.

      Currently, some collectors think that this is a Multiple Struck Coin.


I wondered this is a Multiple Struck Coin.This coin received many times of strikes on the (almost)same spot when it was stuck in the mint press and could't be ejected.The continuous striking caused higher rim to be formed,and caused the lettered edge to deformed.The impact on multiple struck on the same spot may caused high temperature and and resulted the coin, especially smaller denominations to become darker in colour. You may find that the center of the coin is thinner,due to the impact of continuous struck,the metal was pushed to the edge,hence,form a higher rim.

     And it could be a coin which was not struck by the third collar die. (Nu Coins and Notes)

Hi mnfaj,
We have found a 20sen coin also more or less like that.
Thanks for sharing :)

Just my opinions.

Hi whycollect,
Thanks for dropping by.

Hi Dickson,
Thank you for your explanation. I am still cannot imagine clearly of how coins are minted. Maybe I should find time to watch it on youtube or something. But for our 50sen coin, does all three dies, namely obverse, reverse and edge dies are being struck to planchet simultaneously? Hmm. Are these type of error coins rare or scarce to be found because I cannot find anything like this on internet which are properly documented.

By the way, the surface of the coins does show some sign of high temperature, in my opinion. And it is of slightly smaller diameter too.

hello..i have exactly same coin like yrs,1973 50 cent...some said that these kind of coin is counterfeit...i'm confused..if it's fake so the coin has no value at all?
i want to know whether tumbled coin has collection value or not..thanks..

Hi Rahmat Selamat.
If your coin is similar with my coin here (having raised edge), then it is a tumbled coin.

This type of coin is not a counterfeited coin. Usually counterfeiters will try to mimick the counterfeited coin with the original one.

In my opinion, thumbled coin does not has any collection value at all. Because tumbled coin is a damaged coin. Unless you want to keep one as your memoribilia for your first tumbled coin found in your first washing machine. :D
