What Coin Series Are Weak Or Strong?

The classic commemoratives are a solid buy at the moment with the market on a nice steady increase. It's not beyond the realm of a possibility for the market to suddenly spike. Another thing I've noticed, in the past five years alone, is how modern clad coinage are bringing strong numbers in the upper mint state grades. Obviously they are getting some overdue respect.

I've been a collector for a while, based on my experience the following have all experienced price appreciation the last few months.

Peace dollars are doubled what I paid 2 years ago
ASE have increased 50-75% just in the past few months
Indian Head cents are about 35% more expensive in the past 6 months
Modern silver coinage is anywhere from 25-100%, but this is selective as an example common date quarters haven't increased much while the stare quarters and ATB are higher cost.
Slabbed coins have increased from 10%-45% in the past few weeks (based on the 7070)
In terms of not seeing much growth, regular ms64-65 Franklins are still inexpensive
I also haven't seen much increase in common date (none PM) raw coins

The above is based on what I buy and research. Since I don't collect gold or Morgans can't say much about that market.
