The second series of sen coins entered circulation in late-1989, sporting completely redesigned observes and reverses, but predominantly retaining the design of edges, diameters and composition of the previous series' coins as of 1989—the 1 ringgit coin an exception. Changes include the depiction of items of Malay culture on the obverse, and the inclusion of a Hibiscus rosa-sinensis (Malay: Bunga Raya), the national flower of Malaysia, on the upper half of the reverse. The second series was designed by Low Yee Kheng.
The 1 sen coin with diameter of 17.78 mm, thickness 1.26 mm and weight at 1.74gm is a Copper Clad Steel planchet, plain edged. On the obverse is a Rebana ubi design. On the reverse is Bank title, value and year of minting.
This is a rare specimen coin struck with a date of "1988", instead of the regular year of "1989" as the year of minting, the official launching was on 4th September 1989.

Pattern coins were made as test coins during their developmental stages. They might represent the birth of a new issue, or an experiment with a new alloy.They usually are the coins never produced for use in commerce.

Pattern coins can be categorized as:
True Patterns: are used to test a design with the intention of using the coin for circulation.

Experimental Pieces: are usually variations of a coin, i.e. planchet thickness or diameter, shape or composition, etc.
Regular Die Trial Pieces: are regular issue coins struck in a metal other than used in their circulating variety. They are used for press setup or trying a new way to strike the coin. They are also used as inexpensive samples for study.

There have been many metals used in pattern coins. Some of them are: copper, copper-nickel, aluminum, brass, bronze, gold, nickel, lead, pewter, tin, steel, zinc and silver.

The trial pattern can be struck on both sides of the coin, or on just one side.
If it is struck on just one side, it is known as a “splasher”. Pattern coins are beautiful, rare and historically significant. They are real bargains when you consider their actual rarity. Pattern coins are an important part of the coin development process, and are rarer than any regular issue coin.

I was very lucky to be given the chance by Mr. AG to share with you about this very scarce Straits Settlement pattern dollar coin. It is a Uniface Silver Pattern or Die Trial for the Obverse of the Dollar. An Undated (1907-1909) Straits Settlement Silver Dollar with a diameter measured at 34mm.
This very scarce (the only piece known) Straits Settlement Undated (1907-1909),Uniface Trial Silver Pattern Dollar was auctioned at Balwin's London International Auction few years ago with a realized price of 3,220 pound (about RM16,000) as raw coin. Today, it worth many folds!

Thailand  Die Trial Struck, Pattern And The Original Coin (1971)

Rarity:RRRR

On 19-03-2011, I posted this article "Thailand Hub & Die Trial Struck", It is about a Die Trial Struck of a 1971,Thailand 50 Bath commemorative coin, i.e.:"IN COMMEMORATION OF 20TH ANNIVERSARY OF THE WORLD FELLOWSHIP BUDDHISTS ".(BE. 2493-2513), a silver coin, its regular issue was struck in 0.900 Silver.



On 18-06-2011, I posted a related article "Thailand Hub and Die Trial Struck And The Original coin (1971)", when I came across an original piece of this Thailand 50 Bath commemorative coin on first week of June.2011.


Now, I found  a pattern coin of this Thailand 50 Bath commemorative coin minted in copper material.


Hub Trials and Die Trials are usually uniface (struck on one side) impressions using either the obverse or reverse die. These Die Trials can be from finished or unfinished dies. These are deliberate strikes to test a certain design or example. Sometimes hubs are used, rather than the actual finished die. Metals other than the adopted composition are frequently used to strike hub trials and die trials. They are sometimes struck in copper and white metal. Other times they are struck in softer metals like tin or lead. There are even some examples struck in wax and on cardboard.

Technically hub trials and die trials are part of the pattern family. Many pattern enthusiasts have always wanted a hub trial or a die trial piece to go along with the specific type or denomination of pattern(s) that they collect. A new demand has emerged for hub trials and die trials.

Collectors of major mint errors are placing these in their collections because they are unusual, exotic and unique. Even though they are not mint errors, they are aggressively sought after by people who collect off-metals, broad strikes, uniface strikes and coins struck on larger planchets.

Is this a specimen, pattern or trial strike coins?


Few days ago, a customer sold me a bunch of coins, among them,I found this two pieces of unique Malaysia Bunga Raya series 50 cents coins.


I am puzzled on the errors,but so far I have not find the right category to prescribe  them. Are these a specimen coins, pattern coins or a trial strike coins.


Assembled a forgery coin dated 2010, unifaced with details design on reverse but absent of designs on obverse and is concave in shape like a bottle cap, plain edged,was struck on aluminium material, weigh is 3.24gm compared to the normal weigh of 9.33gm.


Next, is a genuine 50 cents coin dated 2004 with similar features,but with lettered edge and concentric lines on the reverse,weigh is 2.98gm.(Normal: 9.33gm)

I seek your feed back.

Traditionally,only pattern specialists pursued hub and die trials.Beginning in the late 1990s,however,there have been increased in demand for these pieces among error coin specialists who feel that these pieces would fit nicely into their collections due to their exotic appearance and the unusual circumstances under which they were produced.
