Diaglo - your GM must have been really mean with the treasure, after all gp = XP! 
IMC 1e we played 5 times a week for most of the period ca 86-91, starting ca 3rd, I think (but am unsure) the PCs were in the high 20s at the end of this period. Although play became much more occasional 91-99 advancement speeded up due to 1e's flat xp/level, hence Thrin getting to ca 118, or 115 levels, in about 13 years of play. Other PCs reached deity status but most subsequently died & none got nearly that high.
Edit: Actually thinking about it, 115 levels in 13 years is still well under WotC's recommended 19 levels (1-20) in 1 year.
