I'm looking for something that may not even be out there. I need a crossover from Breen numbers to Gerry Fortin's F numbers and or CPG numbers. A cross like this would be a big help for me.
I assume you have some of your coins attributed to Breen numbers. I can't help you with a cross-over but I'm sure Gerry will be happy to give you whatever information he has. Give him a call. I think he's still in Venice, the snow not having melted yet in Maine. Also, maybe give Len Augsberger at LSCC a call.
The Greer book is here https://archive.org/details/compguidelibdime1992lawr/mode/2up - Breen numbers are mentioned in some of the blurbs but I don't see a cross reference. My Kindle CPG shows Greer, Fortin, Coneca but I don't see any Breen.
I started using the Breen numbers in my records, when his book came out. I bought the Greer book when it came out but never crossed it to my records. Great book even after all these years. I have been using Gerry's website but it's a slow process. I'll contact him. Thanks to all for the information.
