Brought home this Liberty Head dime collection. What should I be looking for?

I was at a best friend's grandpa's house and looking through a room full of coins! Plenty of key dates, complete series, and of course album toned beauties (Everything was blast white when purchased) all at my fingertips. I was in heaven! I noticed this complete set of Liberty Head dimes was unfortunately in a PVC album (Does PVC feel sticky? The coins are sticky..)
I offered to bring it home with me and see what I could do for the coins. I know nothing of Liberty Head dimes and would like if you would share with me the basics. (Major varieties? Overdates? Key dates? Etc)
Here is the extent of the damage. Think it is fixable?

That 99o is a great date ... doesn't look like it has PVC ... but it could be there.
Barber or Liberty Head Dimes ... great series. 1893/2 ... 1893 S/S (wide repunching) ... 1901 O over horizontal O ... 1905 micro O (compare to another O mint, noticably smaller) ...
94-S ??
