How Far Back Can We Go? Third Edition! Ended At 1487 Waiting On 1486

Grand Duchy Lithuanian half-groat 1511

@Spence,my Lithuanian half-groats will end very soon - February of 1509 is the earliest date we have the written resources about the coinage of the Lithuanian half-groats by Sigismund the Old. Yes,there are three pieces of 1508 known, but these seems like counterfeits or patterns.
Sigismund the Old was Grand Duke Lithuanian and Polish king, so we can find Polish and Lithuanian half-groats with his name (Polish and Lithuanian monetary systems were absolutely different at this time ).

„ Lithuanian half-groats penetrated the Polish market since their value was 20 per cent higher than of the Polish ones. This aroused dissatisfaction among the Polish nobility. At the Piotrków Congress in 1501, Polish representatives for the first time demanded to equal Lithuanian and Polish coins in weight and value, as Lithuanian coins were by a fifth more valuable than Polish. The Act of Mielnik, signed in that same year, provided for common money, but the Lithuanian Seimas did not approve this Act." ( http://www.pinigumuziejus.lt/wp-con...atalogas.pdf )

Poland -- 1510 1/2 grossus/groschen (Gumowski 480) :

There are last my Lithuanian dated coins, half-groats of 1509, first year of mintage by the rule of Sigismund the Old. Rare type of Knight (with scabbard), inverted E in MONETA and two different reverses.

Agreed!

You betcha! Here is another half groschen from Poland. This one is dated 1508 AD and is attributed as Kopicki 408. I really like how the number 8 looks like two links of a chain.
