All About Pocket Knives

I think I have posted about this knife quite some time ago, but here goes again if so. This is a knife that I ended up with after my Dad died. The tang stamp shows an age 1905-1914. It has been used hard and one of the blades has been repurposed. The tang stamp is
W R Case
& Sons
Bradford, PA
There is also a stamp on the secondary blade, which has been made into a punch. 122 then 3 or 8 and then B or R or P. I include photos of all this and maybe some sharper than my eyes person can make it out.
my question is "Is this knife too beat up to be worth much on the market?" I have seen some older Case knives of the same time frame that look real nice going for close to $1000. I don't expect this one will come close to that, but I would like to know a range. I should talk about the blades snap and etc. The master blade is sloppy like a broken spring, but I do not see a fracture. the secondary blade has lots of snap both ways with a half way pause. Thanks for looking.

Very nice!! It is a 1228 PU pattern.

The original Teardrop.

I am always amazed at how much knowledge is floating around on this site. Thanks

Regarding value, another point to consider is condition, especially with Case knives. There are a lot of Case knives out there, and there are a lot of Case collectors out there. I've found that a Case knife is either MINT, or anything other than mint. And collectors with money are mostly looking for the best possible condition knife for their collections. Your knife is a rare pattern from a very old era of Case, so there is some value there for sure. But condition hurts it a bit. I'm not well versed enough to put a number on it though.
