145. 10 sen malaysia 1981 die clash obverse and reverse unc

image 1: obverse and reverse of the coin

image 2: die clash mark with their respective pairs
        Die clash error seems quite common, especially with our old 10 sen parliament series. This is the first specimen that I have encountered in uncirculated condition. Usually die clash marks on both obverse and reverse follow directly the mirror images of their respective opposite side. But on this specimen I notice that clash die marks happen on a rotated mirror image of their respective opposite side, as indicated on image 2. But still this coin does not possess any degree of die rotation error? Could it be the clash of the two dies happened in rotated position, then later were being altered back to its original position? Images are clickable in order to view it in a higher resolution.

144. 5 sen malaysia 2006 curve clipped planchet

image 1: obverse and reverse of the coin

    This is a 5 Sen coin, dated 2006 which has a curved clipped planchet error about 2% located at 9.30 o'clock on obverse.

    This error happens when a coin was struck on an incomplete planchet. It is possible to have curve-shape clip, straight clip, and ragged clip. Several numbers of clip can take place on one planchet. Size of the clipped area and number of clip are the main factors of how interesting the error coin is.

    There are several ways to identify whether the clipped planchet is an original due to missfed blanking machine or a post mint damage due to cutting.

  1.  Examine the area opposite directly to the clipped area - An original clipped error will cause this area to have weaknesses, especially at rim's area. This effect is called Blakesley's Effect. Refer to image 2

  2. image 2:  weaknesses of opposite area of clipped area due to Blakesley's Effect

  3. Examine the letterings of legend near to the clipped area - Sometimes extreme fishtailing can be observed. Refer to image 3.

  4. image 3: fishtailing of alphabet "L"

  5. Examine the detail near the clipped area - Especially at rim's area, those area near the clipped area will have the fade away effect.Basically the rim will taper off into the clip. On a fake clipped coin, the detail will just come to a sudden end. Refer to image 4.

    image 4: tapering on the rim

  6. Examine the clipped end - A genuine one never show a raised edge of metal, which indicates shearing and the details bordering the missing metal should not be crispy. On a thicker coin, sometimes the clipped end appeared to be like have been bitten, producing two-layers-like edge.

       This clipped coin was discovered among these coins. Can you guess how many pieces of coin are there? Hint: those coin fills up the whole cooking gas tank over there.

142. malaysia 1 sen 2007 die crack error

image 1: obverse and reverse of the coin

     A nice 1 cent coin of Malaysia, dated 2007 in uncirculated condition with original mint luster. Die crack line can be observed on its reverse. The die crack line starts from the rim at 6 o'clock heading up through "E' and "1" until it reaches the hibiscus flower. Upon close inspection I think this is an RTR Die Crack Error as a faint line can be observed at around 10 o'clock.

141. Terengganu Coin Pitis Sultan Baginda Omar 1849

image 1: obverse and reverse of the coin

image 2: highlighted inscriptions on the obverse

        This is the same coin as I posted earlier here in a nicer condition. For those who are collecting Malay Sultanates coin, I suggest that this coin is a must in your collection. I repost the information of this coin for your convenience.

       Lot of these coins were found to be off-centered struck. A pair of perfectly-centered and off-centered struck coins would be good for collection I suppose.

      I think a price range of RM5 for poor condition to RM50 in a top grade condition is suitable for this coin.

140. Malaysia 20 sen 1982 UNC/BU TONED

image 1: obverse and reverse of the coin

        While scrutinising some coins few weeks ago, I spotted this piece among the coins. Nothing special about this coin. Not a keydate issue particularly, nor an error coin.

     This coin shines among others. With its soothing yellowish tones, I think this coin's grade falls between UNC and BU. Too bad the tones cannot be captured well by my scanner.

     By the way, how come this nice, uncirculated coin with nice tones survives the ravages of time, weather and handling, for about  more than 20 years?

image 1: obverse and reverse of the coin

    This is my another Johor Tin Katun. Three holes exist on this coin, probably due to improper tin flow during its casting process. Varieties with other numbers of pusat may also exist. I paid around RM33 for this piece with a dealer in Kuala Lumpur. Maj. Pridmore had classified this coin  in Group C - Hexagonal, Class V - Pusat (dot). Please look at my other Johorean tin katun coins. Can you find the 11 dots?

   In a recent meeting with a collector few days ago, he had mentioned that he had read somewhere in a book that the hole(s) on the katun coins are intended, not due to improper tin inflow. The hole(s) serves as a means to attach a string through it for easier handling. But most of the katun coins do not have the holes, could it be they observed how easy Chinese traders handle their cash coin using strings. And plus, some of the holes look in nearly perfect round.

    These are examples of 11 dots and 8 dots of the same coin. Both of them have hole too!

138. Malaysia 20 sen 2008 Doubled Die Variety Reverse Type V Pivoted Hub Doubling

image 1: obverse and reverse of the coin
    Now I shared the same feeling as blogger whycollect had anticipated in his post, not too long ago. Mixed feelings between happy and frustration. Being happy for discovering another doubled die coin, which is not easily acquired as nobody is selling them right now, and frustrated as the condition of the coin is not in a desirable state.

   This is most probably a Type V Doubled Die Reverse (DDR) - Pivoted Hub Doubling, Counter Clockwise Direction (CCW), pivoted at 10 o'clock which occurs when the working die is not properly aligned with the working hub, thus rotated during one of the hubbing processess.

   The doubling is clearly stronger at one side, which is the right side of the reverse. The doubling will increase as you travel around the rim until you come to the strongest point, and starts decrease till you return to the point of no doubling. This point of no doubling is called pivot point. From this specimen, the pivot point is most likely located at 10 o'clock position.

    This is my second specimen of this variety. This is my first specimen in a nicer condition.
