Are these worth anything?

Last time I checked, they were selling for $5- $15 depending on year, with 68-70 obviously the higher end.

I got a shiteload of those from when I was a kid in the mid 70's to mid 80's and also a crapload that my uncle got in the early 60's to the early 70's...and a few when I had a relapse in the mid-90's, then another when the LX came out.
