The Longacre's Ledgers, that Rick mentioned are quarterly magazines written by Fly-In Club members and edited by Rick. They contain a wealth of knowledge on the Flying Eagle and Indian Head Cents and are available on-Line and can be found by searching on topics through Google and other search engines. Just include the words "Longacre's Ledger" with the subject about this series you are searching for. http://www.fly-inclub.org/files/ll_vol_1-1.pdf
