Lunar Voyage Cachets

‘Lunar Voyage Cachets’ were made by Robert Rank. I’ve seen a couple of early covers from 1966/7, and then it seems they exist for Apollo 7 onwards. I’m not sure about the earlier unmanned Apollo missions, can anyone help? My small collection is shown below. Please note: the blue Apollo 8 cover and the purple/green Apollo 9 cover may not be ‘Lunar Voyage Cachets’, but in that case I’m not sure what they are !
