I have been on google and saw all the thalers but the g at the bottom I have never seen the word aust indecates it was minted very early 1800 upwards if it was avst it was minted later and not in austria so google it but I dont think its authentic I think its fake but its only my opinion google it under thaler id they where minted till 1986 if I'm correct there is a lot of diff designs each one indicates a diff year and country but that G never seen it on that coin

Check it out thalers only got minted from 1780

Thalers were minted prior to 1780...1780 just seems to be the date that was minted for a couple hundred years. This design started in 1764 and ended in 1780.
They did have the G in that location. As for authenticity, I do not know.

Its better NOT to answer to a new guy if you are not sure for your reply

That coin looks very genuine to me ...but to double check can you tell me if it has the letters "S.C" under Maria Theresa's bust. If those letters aren't there then I will have to check my reference books to see if some MTT in 1765 were struck with out the "SC".
MTT were first struck in 1741. That coin was struck by the Guenzburg mint which was established in 1764. A significant factor leading to the setting up of the mint was the trade in Maria Theresa Thalers. Bankers and bullion traders in Augsburg(relatively speaking "just down the road") had been buying Maria Theresa Thalers from the Hall mint in Tyrol. After the Guenzburg mint was set up the demand for MTT from Hall dropped. Augsburg bankers on sold the coins to traders in Marseilles, Livourno and Genoa who traded the coins,at that time, in Alexandria for Coffee beans, silk, aromatic gums and pearls. The G is the Guenzburg mint Mark( changed later to "H"). The S.C., that I expect is under the bust, is the mint signature. As Henry has said photographs of the edge would help. This is a true original thaler value is about €120- €250( wide range because going from memory) Restrikes are all 1780 dated MTT struck from 1781 on. Original 1780 MTT are extremely rare except for the Kremnitz mint(Hungary) 1780 strikes( Madonna and Child reverse)

Edit. this is from memory and I realy need to double check it to be sure so don't quote me yet. The 1765 MTT from Guenzburg was restruck in 1766 and 1767. Maria Theresa was Widowed in 1765. The bust was changed to a widows bust and it was unpopular in the levant. Another factor is in 1766 another Thaler was produced in Guenzburg the Burgau conventions thaler. So the MTT struck for trade in the Levant were struck using the 1765 dies, Complaints about the widows bust were such that around 1772(again from memory a new compromise bust was produced..... one very close to what we see on the MTT today. The main problem with the First Widows bust was that the Brooch was either omitted or it was partially obscure( depending on mint). The brooch had very quickly become a Authentication feature in the Levant. So removing it or partially obscuring it led to quite strong customer resistance more importantly those coins could only be traded at a discount so killing the profits European bankers and traders were making out of the coin.

I have found these informations.Its a

Btw the 1765 Guenzburg MTT is quite common. It shouldn't be described as rare. Ok checked my references 1765 was a transition year. THE SC signature was introduced during 1765 so you find MTT with and without the SC mint signature
