FS. Cat. D318 and ? intake and exhaust valves.

Is there any demand for used engine valves? I have some that I am sure have been used but they are not burned up. They have been stored for many years and I don't think the man would have kept them if they were no good. The only thing I see wrong with them is the rust on the stems. Some only have stains in the same area. I think that area would be under the spring and not in the guides. I can do photos if there is any interest. Anyway, I would like to know if used valves have a market. What I have are:
12 each EX 1P2629
5 each EX 5S6449
3 each EX 4N5653
9 each IN 6H3026 SOLD, thanks
10 each EX 4F212 SOLD, thanks

Here are a couple of photos. I selected two of the worse from each p/n to photo.

Sir, thanks again for the helpful ID of my parts. Are these, judging by the photos, good enough to use or are they trash? Regards, keith

Margins look good on the seats, not alot of wear on the stems.
They are worth something to someone else.

All parts are gone, thanks.

Glad to see they found a home, they looked to be in good shape.
