Is there a resource to find out what specific year re-strikes were produced? I have read up on the original but am curious as to when this might have been struck.
I know of this resource for the Silver 1780 Thaler restrike: http://www.theresia.name/en/svariants.html I haven't seen anything similar for gold restrikes (they might all be too similar to tell even an approximate date).
As far as I know, your coin, an 8/20, is not a re-strike: Austria-Hungary partially adopted the Latin Monetary Union (LMU) at the end of 1867 and starting in 1870 all trade gold was dual denomination. 4 forint or florin/10 francs and 8 forint or florin/20 francs as per the standard LMU weights and measures. As this was the new trade currency they took the place of the ducat. Essentially the 8/20 was the new ducat and the 4/10 the half ducat. If you are asking about re-strikes of gold Ducats of Franz Joseph I, none of the 1915 Ducats were struck in 1915. Those are re-strikes.
Here are a couple links that I found informative . . . . .

About the Maria Theresia Taler there is also good information here: http://www.coinweek.com/featured-news/the-maria-theresa-taler-a-coin-for-the-centuries-part-i/2/ and here http://www.coinweek.com/featured-news/maria-teresa-taler-coin-centuries-part-ii/
Thanks for all your thoughts. This coins details are as follows, look at the last date struck and it clearly says re-strike with no mintage quantity https://en.numista.com/catalogue/pieces17723.html
Interesting. This confirms the same. https://www.ngccoin.com/price-guide...s-km-2269-1870-1892-cuid-1049869-duid-1224840 Z
Didn't know that the 8/20 issue from 1892 was a re-strike. Learned something new . Thank you @ZoidMeister and @expat
Just because it's a "restrike" does NOT imply that it is "modern." Austria made a few restrikes after the demise of Frantz Joseph I and the passing of the old feudal form of governance leading into WWI. Z Franz Joseph I certainly was an interesting old character.
I have heard this also. It is why it would be interesting to find out when their re-strikes were done
