ET AL.As used in this group it means the
Roman Imperial Coinage.
Catalogue ,somewhat out-dated but loved by mainstrean collectors,in particular when after a coin they read S or R ( best if accompanied by a 5 or 4 than by a 2) that very often does not reflect the real
rarity of a coin.
Hope this helps.
