Hi Bob,
One of our members walked the convention selling sets of the 5-25-100.
Due to my failing memory, I can't recall who or how much he was selling them for
but it was cheap enough for me to have bought a set.

TCR-8 will have them valued much less than TCR-7. James C. says that a hoard
was found and C-W lists them at 50-120-150 for mint condition, which is what
my set is.
