bulk numis as a store of value

Here's a question that I got curious about as I was thinking recently. Concerning bulk numi coins like common wheat pennies, buffalo nickels, indian pennies, v nickels, etc.: does anyone know about their performance against inflation over time? It seems like the common wholesale price for wheats currently is about 3.5x, what was it like 20 years ago? Or 40? Anyone have info like this on wheats or any of these other coins?
