What a Grass Memory card is worth
The most valuable Grass Memory on this list is Grass Memory from SM - Team Up at $0.39£0.29€0.34, and the 1 priced copies across 1 sets are worth $0£0€0 together. Most of that sits in a handful of printings: the older the set and the scarcer the print run, the wider the gap to the rest.
Grass Memory is printed in Japanese as well: 2 cards across 1 sets, the most valuable of them Grass Memory (Mirror Holofoil) from GX Ultra Shiny at $4.89£3.66€4.27. Switch the list above to Japanese to read those, or to Both to rank the two catalogues against each other.
reverse holo printings are priced separately from the standard card, because they do not trade at the same money.
If you are trying to identify which Grass Memory you have, the set name is printed on the card and the collector number sits in the bottom corner. Open the card here and the page carries every printing of it, the graded prices, and whether grading the copy is worth the fee. Sets to start with: SM - Team Up.
