That’s a problem if you are trying to make comparisons that mean anything. It’s the same as comparing apples to coconuts. 
My first house in 1968 cost $19,000. The house I bought in 2012 cost $550,000.
That doesn’t reflect a 30x increase in any meaningful way. It means the cost of the house I bought in 2012 was almost four and a half times the cost of the 1968 house. (($550,000/($19,000*6.6)) = 4.39
