Let me clarify slightly for the common man.

I had been buying lots of mid grade and up of commons and semi-stars (with an occasional star thrown in for the last few years.
Two years or so ago I could buy a lot of cards from the early to mid 60s pretty commonly for about 40-50 cents or less per card. These are consistently going for 70 cents and up now. I have seen some 300 card lots go for $400.

Essentially, I believe the market for vintage cards is more competitive than it was 3 or 4 years ago. I can't give a fair reason why, but it's becoming obvious that some of the common prices are rising.

As well, cards in the mid 70s all the way up to the mid 80s are going for more as people are seeking cards in high grade to slab.
