There seems to be quite a bit of variation in the style of portrait on these coins, and the style of the shield. Here are some from the
CoinArchives search for "Sachsen and thaler and 1780" (out of 120 hits total):





You'll note there are two similar-but-different types here, with two different reverse legends: the "mining thaler" with main legend "Der Seegen des Bergbaus", which translates "The Blessing of the Mines". The other is the "convention thaler", with the main legend just the weight "X Eine Marcke" (1/10th of a mark).
As to the purchasing power of a Saxon thaler, it'd be about the same as an Austrian "Maria Theresa thaler". Both are coins weighing 28.06 grams of .833 fine silver. The "convention" mentioned above was an agreement among many of the member-states of the Holy Roman Empire to strike thalers of the same weight and fineness, so they could circulate freely in trade across the borders. Spanish dollars are slightly heavier and of slightly finer silver, so would have had slightly more "purchasing power". In those days, a coin's silver content was the chief determinant of it's value in trade.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
