Identifying German bayonets

Hey guys!
I am in possesion of three WW2 bayonets, that were left to me by my grandfather who got it from some German soldiers, when they left Denmark in 1945.

They are all three quite sharp, and in very good condition. The longest bayonet (43.3 cm) is in picture nr 1, bayonets 2 and 3 are identical, except for the writing on them. Their length is 38.8 cm. Bayonet nr 1 has very little writing on it, a "Z" or a "2" in a circle on the blade, close to the shaft. Bayonet nr 2 has the following on it: "8347" on one side, on the blade close to the shaft and what looks like an oddly shaped "q" beneath it. The other side says: "S/155G", again on the blade, close to the shaft. Bayonet nr 3 has following: "301" and a "J" beneath it on one side, and the other says: "J. Sch.". The sheath on the picture is original and is made for bayonet nr 3, because it has the exact same writing on it.
My question is, where did these come from, and what might they be worth?

Thanks in advance for any response.

 

Forgot to say, on the third bayonet, on the sheath, beneath the J. Sch. it says 1939.

 

you have one 1898-1905 German Mauser bayonet (WW1 version) and two K98 Mauser ones (the WW2 version ones) .

 

Just something to point out to actual members here that may want to learn something beyond cost....the 'G' code marking on a K-98 bayonet indicate that the bayonet was made in 1935. You can see the same S/ code with a letter 'K' as well...this denotes that the bayonet was made in 1934. The S/ Codes are still a small mystery as not all of them have been deciphered to this date. The S/code system was a way to keep the manufacturers protected while the Treaty of Versailles was still an issue.
