There are a few things to realize about a 1780 Maria Theresa Thaler:
Your coin was NOT minted in 1780, the Austrian mint has produced Maria Theresa Thalers fixed at Maria Theresa's death in 1780, most likely your coin was made in the 20th or 21st century. That doesn't mean your coin is worthless it just means that your coin isn't several hundred years old. Since they are restrikes, they don't have much of a premium over silver value, today they run around $25-30 depending on silver price and the condition of the coin.
The value of a 1780 Maria Theresa Thaler can vary depending on its condition and any unique characteristics it may have. Generally, these coins can range in value from about $20 to several hundred dollars, with rare or well-preserved pieces commanding higher prices. It's best to consult with a numismatic expert or use a coin appraisal service to determine the specific value of your coin.
Most Maria Theresa Thalers are modern restrikes and generally trade for close to silver melt, about $20-21 at present. Don't let the date fool you, nearly all the coins were minted well after 1780 and indeed continue to this present day, still with the date of 1780.
The Maria Theresa thaler coin was first minted in 1741 but after 1780, has since been dated to 1780. The coin was once accepted as a form of global currency, but is today seen as a collectors' item instead.
The Maria Theresa thaler is still being minted with the 1780 date. It is basically a bullion coin containing approximately 3/4 ounce of pure silver.

First, it is highly unlikely your coin was struck in 1780, the Maria Theresa thaler has been struck in large quantities from 1780 all the way to the present day. If you are really interested, there are ways to determine by the die if yours is an older strike or a newer one. But generally, these coins sell for silver scrap, or perhaps a bit more. You should easily be able to sell it for $20-25 depending on the price of silver.
Austria: but also Italy, UK. Belgium, France, India( using Royal mint dies from the UK) also possibly Russia back in the dayss of the USSR
She died on the 28th of November 1780 at the age of 63 because of heart failure.
I think that you are referring to a Maria Theresa thaler, a silver bullion coin (for use in international trade) originally produced for in Austria-Hungary in 1741 years ago and still produced today with a "frozen" date of 1780. The thaler is 39.5 mm in diameter and 2.5mm thick, weighs 28.0668 grams and is 83.3% fine; it thus contains 23.3890 grams - or 0.752 troy ounces - of silver. With silver at US$18.50 per troy ounce (as of mid January 2010), that would make the "melt value" about US$13.90. Numismatically, it's is difficult for the non-expert (and I place myself in that category) to differentiate between a thaler produced 200 years ago and one produced last Thursday. While the former would probably be worth more than the latter (or at least some of the former; the thaler has been produced in many different countries over the last 230 years), it would take a specialist to be able to identify and value those that are particularly dear.
The value of a Theresia silver coin can vary depending on its condition, rarity, and current market demand. It is recommended to have the coin appraised by a professional numismatist or check online auctions or coin dealers for current pricing information.
Wish I had logged in for the other coin questions. You like eceryone else need to describe the coin much better. In your case it is at least somewhat understandable but if you got as far as knowing it was Maria Theresa why not tell us the origin. The coin was produced in several countries in several provincial mints. It could be worth as little as $5 and as much as $200,000. You need a pro and in reality maybe 2 if the first one says it is worth something
The value of a 180 einen thaler coin can vary depending on its condition, rarity, and historical significance. It is recommended to consult with a numismatic expert or use online resources such as coin pricing guides to determine its specific value.
