Few Coins To ID | Assorted Early Polish

Nr. 5 is a solidus from Elbing
Nr. 8 is a solidus from Danzig (civitas Gedanen = Danzig) in the name of Sigismund I

Nr.7 is also a solidus from Danzig, possibly in the name of Casimir IV

#1, #2, #4 and #9 - there are, probably, coins (half of grossus?) minted in Hungary during reign of Louis II Jagiellon (I can see LVDOVICVS R UN ET BO on the reverse).
#8 - definitely Gedanen (or Danzig) coin
#7 - I've thought that it might be Casimir IV solidus from Gedanen
#5 - definitely Elbing coin

For now, my guesses are right, thanks!

To sum up, and add my own observations:

#1 is dated 1526, I think; Louis II of Hungary and Bohemia was the only coin-issuing "LVDOVICVS" I could find, and looks like DCH is spot on with the mint; here's an example of this exact type (half-groschen) and date. Schweidnitz (now #346;widnica) is currently in Poland, near the Czech border; the Duchy of Schweidnitz was Bohemian, which became part of the Hapsburg empire in the year this coin was minted.

#2: just like #1, but dated 1524.

#3: Poland, Sigismund I, dated 1509.

#4: just like #1 and #2, same date as #2.

#5: Solidus of Elbing, SIgismund I, dated 1533 I believe.

#6: seems to have stumped everyone, including me. It's too worn for me to read whole words, but the style of lettering looks older than the other coins here - probably mid-1400's. And, from the design and the only legible word POLON, it's Polish.

#7: what bart said: solidus of Danzig.

#8: Danzig. Being larger, and not having the word "solidus" or "grossus", it's probably a schilling. Dated 1539.

#9: Same as #2 and #4.

#10: Another older Polish coin, not too dissimilar from #6.

I've found #6 and #10

#6 - Casimir IV Jagiellon coin (king of Poland in 1447-1492), half-goschen (it's possible to read MONETA KAZIMIRI on the reverse)
#10 - John I Albert (king of Poland in 1492-1501), half-groschen (it's possible to read MONETA×I×ALBERTI on the reverse)
