A restrike could mean a coin that was struck well after the original striking but using similar or the same dies. I know some of the most expensive American coins are examples of this: the 1804 Dollar (https://en.wikipedia.org/wiki/1804_dollar). None were actually struck in 1804. The first weren't struck until the 1830s. And then there were strikes known as restricts in later years.
So you could have that. But I think the Maria Theresa is also well known for being heavily, heavily copied.
