126. Straits Settlements 20 Cent 1919 Clashed Die & Doubled Die Reverse Type VII (Modified Hub Doubling)

     Clashed die error and cracked die error are not too interesting especially for older coins. But something caught our eyes about the first number "one" and "nine" in the date of the coin (refer to image 3). Could it probably a Doubled Die Class IV, a Modified Hub Doubling?

   I believe so because the doubling shows as the difference between the normal hub and modified hub. Probably the earlier "19" was chiseled off from the hub because it ran off its track. This is an extract from an external source.

Modified hub doubling is caused when a normal master hub is used with a modified master hub to make a master die. Some part of the modified master hub was ground off to make it match the normal hub. During this process, not all the original item was completely ground off. One master hub could have the date set lower, so the date is ground off and it is hubbed with a normal master hub that has the date in the correct location. Since this occurs on the master hubs, a larger number of working dies could be affected. bakercoins.com
 
     Any discussion and opinions from fellow collectors are highly welcomed.

     The coin belongs to bonden.

    Could it be an unlisted SS 20 Cents 1919 Low 19/Level 19 DDR Type VII?

Hi mnfaj,
Noticed die cracks are quite common among these classical coins.
But the '9' sure looks interesting.
Thanks a lot for sharing :)

Hi,
MHD class VII is a pure DD but since it involves the master hub, the doubling can be pretty common if ever it is.(AH rarity 2-5) The obvious modified date is interesting here and it is not easy to pinpoint straight to the master hub unless recorded by the Mint in question.
Other date varieties can be considered/analysed; blundered dates, corrected blundered dates, small date over large, repunched date etc.

Interesting specimen.
cheers to dating!

Hi nu,
Thank you for your comment. If the doubling happen on the master hub, I do also agree with you that the doubling should be pretty common, since usually only 1 master hub was made, and all working dies will have the same doubling as the master hub itself.

I really don't have idea what had caused the ghostly 9 appeared on the coin. Perhaps send it for authentication or finding its twin can give more clues.

Manufactured counterfeit?
