Two Lithuanian pages with mintage years split. I can't spot any difference between two apart from years. One Polish page with all mintage years combined.
S. Sajauskas, D. Kaubrys „Lietuvos Didžiosios kunigaikštystės numizmatika“ – Vilnius, 1993 pages 68-84 has three variants:
1. normal variant from 1508 to 1529 with mix of gothic and renaissance script.
2. gothic script from 1512 to 1516 (year uses only two last digits)
3. Renaissance script from 1528 to 1529 with V mint mark below rider.
every variant has multiple engraver marks and lettering or year errors
