It's no problem at all. I like looking up coins in my catalogues, whether they're my own or other people's. It helps me remember where stuff is in the catalogues. And this batch of coins you've been posting is certainly interesting. So, let's see what we can do with these.
#1: the leaping horse says this is another coin from one of the branches of the House of Hanover, like
coin #1/2 here. The "24" in the imperial orb on the reverse indicates the denomination is 1/24th of a thaler, or 1 groschen. There were half a dozen branches of this noble house that issued coins in the 1600's, but the only one listed as issuing a 1/24 thaler in 1694 is Brunswich-Luneberg-Celle, KM# 349. The damage to this one makes it's value minimal, less than a dollar.
#2: Prussia, 4 groschen 1805 A. KM# 370, .521 fine, again with the damage it's probably only worth bullion value.
#3: Ottoman Empire, Constantinople (Turkey) mint, 1 kurush dated Year 2 of Sultan Muhammad V (= 1910 AD). .830 fine silver, probably a dollar or two.
#4: Brandenburg, 2 groschen 1657. KM# 242, again the damage reduces the value to a minimum. The Electorate of Brandenburg went on to evolve into the Kingdom of Prussia.
#5: Another coin from the Duchy of Jever (same country as your coin #1/1
here). It looks like a 1 stuber, KM # 57 I believe. CV $20, even in this condition.
