Wow, what a coin. These old thalers (pronounced like 'dollars' but with a 't') come from a time when Salzburg issued its own coinage under the rulership of Marcus Sitticus (1612 to 1619). St. Rudbertus was the archbishop at the time, so these coins are called archbishopric. The one in our picture comes from Munzhandlung Ritter in Dusseldorf, Germany, where it is on sale for 550 euros, about $675 US dollars. That is a good price for such a nice looking coin. There is a disfigurement at 12 o'clock and that detracts from value. Without it, the price would probably be 600 euros.
The catalog show 1/2, 1/4, 1/8 thalers with similar patterns and inscriptions. They will be worth less than the full thaler. A full thaler measures 40 mm in diameter, while the smaller denominations are, er, smaller.
Also in the catalogs are square klippe versions of these coins. Square klippes are worth more than the round versions.
For these old coins, each coin stands on its own merits. Wear and eye appeal are the most important factors after damage. Damaged coins (nicks, scratches, cleanings, gouges) always carry much lower values than undamaged coins. Very approximately, here are some catalog values:
worn: $100 US dollar approximate catalog value
average circulated: $350
well preserved: $850
