From 1974 - 1978 I mailed out over 25 price lists of major mint errors. My all time favorite was my first catalog which was photographed, printed and distributed in 1975 by John Devine (Lonesome John) from Newbury Park, CA. It was a 26 page catalog containing the finest major mint errors with photographs, descriptions and prices.
Readers who are starting to collect mint errors will find it interesting to compare today’s prices of major mint errors with those of 1975. It is amazing to see what these coins sold for and what they are worth today!
