I recently came across a large advertisement for a newly built home in a Helena, Montana newspaper  from 1892 (see below). After viewing the sketch of the home and reading the details of the listing, I immediately wondered what it might cost in today’s dollars. Thanks to the internet I found an easy-to-use inflation calendar , entered the needed data, and voila! I couldn’t have been more wrong. Just for fun, respond to this post with your guess, and then give it a try. I hope you have a better sense of the impact of inflation on the value of the almighty dollar-over-time than I.
