1860 A and 1861 A are the cheapest (in Austria Netto Katalog 6 EUR VF, 11 EUR XF), the ones which are not from Vienna are more expensive.
2. type: 1866 A, B, E, V Portrait with more beard (expensive types)
3. type: 1867 A, B, E and 1868 A - 1872 A (expensive types)
In 1859 the Austrian Empire lost a war against Sardinien-Piemont and lost the Lombardei. After another lost war against Prussia and Italy in 1866 the Austrian Empire had to give Venetien to Italy. So the Part LOMB ET VEN was no longer used on the coins.
This led to innerpolitical problems and to the Ausgleich in 1867. This means that the Empire was divided in two parts (Austria and Hungary). After 1867 the Hungarian part of the Empire used coins with Hungarian language, the Austrian part kept using Latin.
4. type: 1872 - 1892 (like the one in the
ebay auction from agekas link)
No Mintmark (because only the Vienna mint was left in the Austrian part of Austria-Hungaria)
The cheapest are 1876-1879, 1884, 1886-1891 (in ANK 5 EUR VF, 11-14 EUR XF)
Special type:
1875 mine Pribram
