Got these notes today in change (hurray payday!!) 1963A - 813 1969D - 1744 1974 - 1915 Still trying to fiddle with my new scanner, and camera is knackered right now.
Quick bump. Just shy of 790 back plates reported, some on multiple series. Please take a look at your 1957 through 1981 notes and check to see if I'm missing any of the back plates. The report (last updated 31 August) can be found here: http://www.teamsaber.com/john/back_plate_survey.pdf John
Another quick update. Now at over 1550 back plates in the survey, over 2000 notes contributed. Now at 39 pages (!) of back plate info. http://www.teamsaber.com/john/back_plate_survey.pdf If you have any 1957 through 1977A with back plates not listed, please contact via the information in the survey.

Newly updated. http://www.teamsaber.com/john/back_plate_survey.pdf If you have any 1957 through 1977A with back plates not listed, please contact via the information in the survey. I especially could use more data from 69A and C. Here's a summary of the back plates per series. Code: Series 1957 1957A 1957B 1963 1963A 1963B 1969 1969A 1969B 1969C 1969D 1974 1977 1977A 1981 # Reported 153 53 34 73 190 72 93 47 74 33 152 231 217 218 20 Lowest 2 311 381 397 480 845 1033 1299 1341 1370 1446 1571 1987 2238 2483 Highest 357 427 447 579 1140 1142 1313 1363 1493 1528 1758 2203 2753 3247 3295
