Assuming this is an inflation problem, you can use the consumer price index (CPI) to estimate.
The CPI is a measure of consumer prices compared to a base year value, usually the price in 1982.
CPIn / 100 = (Price in year n / Price in 1982)
The CPI for 2010 is ~218. The CPI for 1995 is ~152. The CPI for 1982 is 100 by definition (hence why we divide the CPI by 100). A 2L of coke is approximately $2.25 from a cursory search over the internet. Therefore
2.18 = (2.25 / price in 1982)
Price in 1982 = 1.03
1.52 = (price in 1995 / 1.03)
$1.56 = Price in 1995
CPI are published by the department of labor and are available at ftp://ftp.bls.gov/pub/special.requests/cpi/cpiai.txt
