First coin is a coin from Brandenburg-(Prussia) In the Krause known under number KM#505 (I think)
I can’t find this coin in the database. Is that correct?? Who can place this in the database? What is the market value??

KM#505, 1/24 thaler, material S, round 21.3 mm, thick 0.9 mm, weight 1.62 gr, year 1683 IE
Second coin is, I think, from Munster stadt (cathedral chapter)

KM#402, 6 pfennig, material Copper, round 25.5 mm, thick 0.9 mm, weight 2.36 gr. Year 1603 ZZZ
How can you discribe the quality of this coin, what is the market value??
Third coin, I think from Saxe-Weimar-Eisennach.

KM#145, 1 heller, year 1794. Is this correct??
The fourth coin, I think from Wurttemberg

KM#270, ½ kreuzer, year 1798, is this correct??
The fifth coin is a "normal" coin fron Germany

KM#109.1, 50 pfennig, however without year. This coin is missing in the database. Who can place thise coin in the database? What is the market value???
