Ecuador - 1917 - 5 Centavos (struck on a 2 1/2 Centavos planchet) - (KM-60.2/KM-61) - Mintage: Probably Unique!

This amazing find was purchased as a raw coin in an eBay auction as a normal 5 Centavos. Sadly it has seen rough circulation, surface debris, and abrasive cleaning. In spite of all that, it is most likely unique, and well worth the cost of certification.

The size of the two coins are very close, so it's easy to see how this coin might have gone unnoticed.

Netherlands East Indies - 1942P 1 Cent - KM #317 - Mintage:100,000,000

Obverse: 3/4 spray around hole in center with value below.
Obverse Legend: NEDERLANDSCH INDIE (Netherlands Indies)
Reverse: Arabic text reiterating the denomination of the coin with flowers below hole.
Reverse Legend: Javanese text reiterating the denomination of the coin.
Edge: Plain

This coin was minted by the Philadelphia mint during World War II for the Dutch colony now known as Indonesia, and it even bears the "P" mint mark just below the date on the right side of the obverse. It also has the Palm tree privy mark (to the left of the denomination) which was used by the Dutch mints to distinguish similar looking coinage intended for the colonies from that intended for circulation in the The Netherlands where the acorn privy mark was used.. The Palm tree appears on nearly all colonial coinage even though in this case there would have been no confusion given the reverse of this coin.

An interesting characteristic of the One Cent coins in this series is that they appear to be struck with medalic rotation while all of the other denominations struck for the Netherlands East Indies were struck with the normal "coin" rotation.

This particular coin is an error coin in that the center hole was punched off center. I had always assumed that the hole was punched into the coin after it was struck, but given the distortion of the hole, it is clear that it was punched into the planchet before the coin was struck.

Netherlands East Indies - 1942S 1/10 G - KM #318 - Mintage: 75,000,000

Obverse: Crowned Shield from the coat of arms dividing the denomination

This coin was minted by the San Francisco mint during World War II for the Dutch colony now known as Indonesia, and it even bears the "S" mint mark to the right of the date. It also has the Palm tree privy mark which was used by the Dutch mints to distinguish similar looking coinage intended for the colonies from that intended for circulation in the The Netherlands where the acorn privy mark was used.. The Palm tree appears on nearly all colonial coinage even though in this case there would have been no confusion given the reverse of this coin.

The primary element on the obverse is the central shield from the Dutch coat of arms topped by the Dutch royal crown. The background (field) of the shield is azure which is a dark royal blue that is represented by horizontal lines in engraving. Also part of the background is gold billetty which are vertically oriented gold blocks, twice as long as they are wide, arranged in rows but not directly underneath each other. A hatched pattern of dots is used in engraving to represent the gold color of the billets. The lion is rampant (standing on his back legs), crowned with a coronet, and is also gold with a red tongue and red claws. In his sinister (left front) paw he is holding seven silver arrows bound together with a gold ribbon, representing the seven provinces of the Union of Utrecht. In his dexter (right front) paw he is brandishing a silver sword with a golden hilt representing the determination to defend their liberty.

This is an error coin that was struck roughly 10%off center.

Lyman Allen #9.04 (KM #181) - Mintage: 31,592,000

General
------------------------------------------------
The Denver mint produced nearly 10 times as many 10 Centavo coins in 1944 as the Manila Mint commonly had in it's most prolific years. As substantial as that mintage is, it's nothing compared to what was to come in 1945. The high mintage of coins in 1944 and 1945 was necessary since virtually all previously issued coinage had disappeared during the Japanese occupation. Because of the high demand, dies were used well beyond their normal life and pieces struck from highly eroded dies are very common.

High mintage figures often imply common coins, but also provide the opportunity for several collectable varieties and error strikes!

This Coin
------------------------------------------------
This particular coin is the normal date variety, but was struck 10% off center. It also appears to have been struck out of collar and consequently, but devices are software struck. Unfortunately, someone along the way decided this coin needed a cleaning. It's still an interesting coin regardless of the details grade.

Lyman Allen #6.06 (KM #180a) - Mintage: 72,796,000
Struck 75% Off Center

This coin is a well struck, dramatically off center error. The devices present on both sides of the coin are magnificent. On the reverse, the sea lion shows the intended surface detail that is almost never seen even on the very finest struck coins. The word "OF" on the highest point of the banner below the shield is evident.. The obverse is just as full of high point detail. The hair and ear are sharp and clear. One of the most important aspects of this coin is that the date and mint mark portion of the design is perfectly centered in the area of the planchet that was struck by the dies. Many that are struck this far off center are undated.

Lyman Allen #9.05 (KM #181) - Mintage: 137,208,000 minted by the US Mint in Denver

General
------------------------------------------------
The 1945D 10 Centavo piece has the highest mintage of any US/Philippine era coin, and is one of only two issues exceeding a mintage of 100,000,000 (the other being the 1944S One Centavo which was minted in both 1944 and 1945, but only dated 1944). The high mintage of coins in 1944 and 1945 was necessary since virtually all previously issued coinage had disappeared during the Japanese occupation. Because of the high demand, dies were used well beyond their normal life and pieces struck from highly eroded dies are very common.

High mintage figures often imply common coins, but also provide the opportunity for some highly collectable varieties and plentiful mint errors!

This Coin
------------------------------------------------
This example is a normal die variety struck on a planchet with a small curved clip at 4:00.
