It would be possible to modify the template so that it is possible to display the previous cost, but this brings the question of what to do if the item has had many different prices over time, where to display the period during which each price was in effect, where to display the reason the price was changed, if we know it, and what to do, if we don't, etc.

Infoboxes should not be overengineered like this. They are meant to be structured summaries of the information presented in the article. If they become too complex, the information should be moved into the body of the article. The infobox is not the article and the article is not the infobox.

I suggest the same solution as  Acebatonfan (a release history table, or giving the information in the article in another way).
