Watch List notes:

TIROL: Sigismund, 1477-1490, AR guldinar, 1486, Dav-8087, Levinson IV-49a, Frey-274, Hall Mint issue, die-cutter Wenzel Kröndl, Archduke standing slightly right facing with sword and scepter with .SIGISIIUnNDVS:*: - ARChIDVX.AVSTRIE. around // knight on horseback right holding flag with date below and 16 provincial arms around, bold strike, never mounted and problem-free, NGC graded VF20, RR. This is the oldest dated thaler, preceded in 1484 by the halfguldiner. Archduke Sigismund had already produced gold florins in large numbers, but the Schwaz silver mine was yielding a huge amount. So the idea for a big silver coin worth a gold guilder arose. However, these coins did not get their name until the beginning of the 16th century, the "Joachimstalers", later called Talers, which were coined in the Bohemian Joachimstal by the Counts Schlick. With a 1:12 ratio of gold to silver, a large silver coin of 31.9g (29.9g fine) was produced.

Estimate: 8,000-10,000 USD
