What Coin Is This? | Maria Theresa One Thaler

Also, how much would it be worth?

I had a look and at the best I can do with these pics is to put it being minted somewhere between 1936-1961 in either London, Bombay, Calcutta or Birmingham. But I could be wrong, you could probably do better with it in hand :)

1772? where did you get that date from? the first MTTs were struck in 1741. Circa 1753 the coin was allowed to be exported for trade. In 1764 the Guenzburg mint was set up... its main output being MTTs that were sold through Augsburg to French and Italian traders for export to North Africa and Egypt(Alexandria). The other Holy Roman Empire mints' MTTs generally traded to more central Ottoman realms. With all that in mind what is the 1772 date about?





You need to look closely at the tail feather formation the mints you have identified ( except birmingham) all used london mint dies and had a 1-2-1 tail feather formation. YOur picture isn't clear enough but to me it does not look like a london mint die struck coin. Please note:

That variant doesn't exist. Birmingham mint only used Brussels mint cut dies so all Birmingham mint coins look like this as do Brussels mint coins:

Be very careful with that web site. Its a great reference but it is not up to date with the latest research.

Edit: I collect MTTs and there is one key thing I have learnt: be very careful what you state about the coin So often in my own research I have had to reassess what I had thought was fact.

The best example of this was a paper on the MTT, as part of a PHD, by an economic Historian: In his first paragraphs he roundly criticized the work of another Economic historian in regards to the MTT. In the following paragraphs that young and eager Writer went on to produce as many errors as he had criticized.
