Hope you are right. The thing is the amount of good condition matching bayonets is getting smaller. Buyers ( not necessarily collectors) are snatching them up as an investment to sell for more in the future. They will want more for resale and unless things change there will be buyers who will pay. Collecting anything can be a gamble. Just glad I got out of muscle cars and old Harley Davidsons. What is to become of them when government enforced electric is the law?Seems some go nuts and others stay cheap. Just the way of it. But in general everything is up, but I can’t see it being permanent.
I copied the photo and looked at it through my PC's enhancement program. It does look very much like a single rune, and the angles of the marking are quite aligned. Also noted of the metal scratches around the frog stud boss, this one is not showing white metal. However, there is a dink on one spot and the upper arm of the symbol appears to be just a bit longer. So, will agree upon further examination it is probably not a rune. However, the marking might have contributed to the strong bid the bayonet received. Had a couple Steyr K98ks with the single-rune stamping on them (back in the 1980s). One had it on the receiver and another on the floorplate (and not long ago sold a floorplate so marked that had not seen the light of day in decades for a friend).Thats a part of carving on scabbard, so i asssume its not a rune but a carving that looks similar.
People are getting priced out of the K98 market; So, now they are doing exactly the same thing to the bayonet market, which is what drove the k98 $$$ up--bidding POS bayos into oblivion. They will only go up, not down. These are not collectors buying them, it's "investors", holding onto trash they know they will be able to sell to some fool on ebay in 2 years.
Yes, prices are on the rise for S84/98 III and Ks98 bayonets. The earlier produced S84/98 I and II have not seen as high of a rise as of yet, but then not as many of those come up for sale as a type III. Often the seller has no idea what their bayonet is and see a type I or II as a non-matching set even if they are in their correct/original scabbard.
