Just happened across these recently. Each have the letter V across the LVM and I am assuming they are early cancellation marks with the V meaning void. But then I don't know for sure. The V on the red chip is hard to see but the V is scratched in on both sides of each chip. These chips are not on Ebay. I am not a collector so am not interested in trading. I will sell these for $25/pair if you are interested. Also, let me know if this is WAY TOO MUCH! Thanks for looking.
