First got name inconsistent with others. Second is listed in wrong country. Coin is minted in Lithuania and got Lithuanian coat of arms unlike his Polish coins. My source tells that coin without A was early variant minted before he was King of Poland or Grand Duke of Lithuania.
Maybe merge information from second into first and delete Polish page. And I will fill regular modification request to sort out other information.
Alexander's denar fineness is 4 lots (.250), weight is 0.345 grams. Silver content is 1/12 of groat unlike later denars.
