Sometimes it is no problem to tell which side has priority or should be considered “heads”. Prows and wheels etc… are clearly ‘tails’ so the other side must be ‘heads’. The knucklebone, not the dot. The acorn, not the sigma. No clue with the thunderbolt vs dolphin. You get the idea.
Crawford for RRC 18 prioritized facing right and had the facing left heads as ‘tails’. This never bothered me until today. I’m thinking about early Apollo imagery for this book chapter now.
The other Apollo that is closest in date is facing left. Should we assume RRC 18 parallels this and give facing left priority for that series? We’d then go back to facing right priority for the aes grave of RRC 26. I’m delighted to note a number of collections have their photographs labeled this way, even if inadvertently:
