Comparison of British Trade Dollars Incuse B versus Incuse C And Incuse B versus No Mint Mark

Posted by slang on December 29, 2008

In earlier article on the brief background of the British Trade Dollars coinage, the British Trade Dollars coin were struck at the following mints:

• Bombay Mint, India which has incuse “B” mint mark in the centre prong of the trident in Britannia’s hand ( however mising on some of the 1895,1897 and 1898 coins)
• Calcutta Mint, India which has incuse “C” mint mark on the ground between the left foot of Britannia and the base of the shield(however missing on a few “1900″ coins)
• Royal Mint, London which has no mint mark(only the 1925 and 1930 issues were minted in London)

This article is on expert observation( Mr R.A. Leonard) of the difference between the Calcutta (”C”) and the Bombay strikings (”B”) for 1901 and 1902.

For the mint mark struck by Bombay Mint, we have:-

• the waves have very clear lines
• the “B” mint mark is in the middle prong of the triden in Brittania’s hand.
• the lower tip of 9 is level with the lower part of 1

For the mint mark struck by Calcutta Mint:

• the waves are not clear at all
• “C” mint mark is incuse in the ground between the bottom of the shield and the left foot.
• the lower tip of 9 is below the lower part of 1.

Another expert(Jerome Remick) made the following comparison from examination of a 1900B Dollar an a 1900 Dollar WITHOUT MINT MARK and noted the following:

• waves on both sides of ship. The waves are not sharp on 1900 and they have about the same sharpness as shown on the 1901C and 1902C dollars. The waves are sharp and clear on the 1900B and show the same sharpness as on the 1901B
• the date where the loop or circular part of 9 in 1900B is of the same size as in 1910C and larger than that in 1900B. The loop or circular part of the 9 in 1900B is of the same size a that in 1901B and smaller than that in 1900. The OO in the date on the 1900 dollar are more oval than the 00 on the 1900B dollar but unfortunately this difference is not too great and can best be seen when the 1900B and 1900 are placed side by side.

The above description is important as the specimens of 1900B with a weak or worn of B mint mark might be mistaken for 1900 without any mint mark

Chopmark In British And American Trade Dollars

Posted by slang on December 23, 2008

A chopmark is small punch mark or counterstamp applied to a coin, usually silver, by an Oriental merchant through whose hands the coin passed. This chopmark indicates that the merchant accepted the coins as being genuine and of full weight and fines. Chopmarks are frequently found on the Trade Dollars of the 1873 to 1878. The above picture is from a British Trade Dollar which shows a very nice single chopmark in Mandarin language meaning “silver”.
