Check out my paper in Errorscope “Why are Copper Plated Zinc Cents Resistant to Lamination?” It is now online at the CONECA website (https://conecaonline.org) under “Errorscope Member Issues” and will soon be in mailboxes. September/October 2019 Pages 10-12 Volume 28 Number 5
I'd love to, but the site says the July/August issue is in the Members Only section, and says nothing about the September/October issue. Could you post a link to the story if it's already available to non-members, or post a reminder here when it does become available? (If you want to leave it as a lure for people to join, that's perfectly reasonable, too... )
I think it is only available to members. Send me your email address and I will see what I can do tomorrow
