What a Goldeen card is worth
The most valuable Goldeen on this list is Goldeen from EX Deoxys at $24.94£18.77€21.96, and the 24 priced copies across 19 sets are worth $94£71€83 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.
Goldeen is printed in Japanese as well: 21 cards across 16 sets, the most valuable of them Goldeen from The Town on No Map at $8.75£6.59€7.71. Switch the list above to Japanese to read those, or to Both to rank the two catalogues against each other.
The highest PSA 10 on record for Goldeen sold for $585.92£440.99€516. 1st Edition and reverse holo printings are priced separately from the standard card, because they do not trade at the same money. Rarities here include Illustration Rare.
If you are trying to identify which Goldeen 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: EX Deoxys, Aquapolis, Expedition.
