I have the 1948 and almost 20 years worth of the same publication. I’ve noticed they are valued any where from a couple hundred dollars to as low as 19$.. I picked them up at a yard sale and just reading through them I’ve come to realize I should have invested in coins a long time ago. For instance gold double eagles were in some cases at around 100$ the same coins today are worth thousands..lots of missed opportunity in the reading. I may list them on Amazon.
