What is the approx value of these strip cards?

Apparently from the early 1900s and don't know who manufactured them either. Any information would be most appreciated. I don't think they are too tough to find.

They look to be the 1923 W580 strip set, but I can't tell from the small pictures for sure. I also can't tell who they are. Aside from the huge names like Johnson and Attell I am not sure there is a ton of demand for them. They look to be in very nice shape.

They are actually commonly found in full strips of 10 for under 75 bucks, though the condition is usually beat up a bit. A lot of them seemed to surface from overseas about 10 years ago or so.

I've seen them attributed as being a foreign strip card issue originating from Thailand but who the hell really knows. They appear legit in hand and are very similar to a US looking issue. I'm not sure how anybody can explain how they ended up in Thailand in the 1920's however.
