Old prices of currency

Does anyone know how much Exalteds/Divines/Regals costed back in closed beta compared to what they are worth today?

I remember Exalteds being traded at a 1:6 ratio for GCPs and Divines/regals being hard to get rid of (with Divines having a ratio somewhere between 1:2.5 and 1:3).

But that was back when races rewarded ridiculous amounts of high tier currency :D.

I searched forums a bit and there are people saying you would get 5 alchs (one stack back then?) for finishing a race.Was that for people that stayed alive without winning?

Rewards were random (the type, not the amount) and awarded for mostly the same things you receive reward points for since open beta.

I remember two iterations of this reward system:

1. Only mid to high tier currency is rewarded
2. Low Tier currency (e.g. Transmutation Orbs, Scraps & Whetstones and so on) are rewarded as well, but the overall quantity of rewards is much higher

If I remember correctly the change from 1. to 2. came along with the last full character wipe pre OB, but I am not entirely sure.
