Historical limit up values for corn, soy, etc

I was wondering if anyone knew what the historical limit up/down values were going back to the 1990s? I know currently it is 30 cents, but it looks like pre-2008 the values were different and I'm not sure what they were. I tried googling, but it unfortunately turned up nothing.

 

i think i remember 20 cents in corn 50 in beans and 30 in wheat but I could be off.

 

FWIW, the limits were 10/20/30-cents for C/W/S up until the huge bull market in 1995/1996. The expanded limits kicked-in at higher prices.
