I happened across a few copies of the collector’s pack the other day they stopped making them, if you’re interested in buying them let me know.
They include:

20 Playable Champions

4 Summoner Runes
$10 of Riot Points for use in the store

We wanted to give players 4 runes that would be fairly powerful, and fit different play-styles. To do so we chose:
Greater Mark of Malice (Improves your critical chance)
Greater Seal of Vitality (Increases your health per level )
Greater Glyph of Knowledge (Increases your mana per level)
Greater Quintessence of Revival (Decreases your Death Timer)

Similarly we wanted to choose 20 champions that would fit different play styles, and also a set of champions that players could quickly pickup and play. We chose:
3 Ranged DPS Champions
5 Melee DPS Champions
2 Support Champions
5 Tank Champions
5 Mage Champions

The actual champions that we are including in the collector pack are:
Alistar
Amumu
Annie
Cho’gath

Morgana
Nasus
Rammus
