For older sets, you'll know if you recognise the set symbol, if you don't the end date on the copyright range printed on the card tells you the year that set came out, and you can find a list of sets in many places (I have usually looked here, but wikipedia and scryfall also have lists) Finding the year will give you only a handful of symbols to compare

While its not as potent as Culling Ritual, its still a solid answer to tokens and has plenty of use cases
