Bottom line: Check the brand and the pattern. If it’s a known maker in a cool style, you might get $10-$15 per spoon from a collector. If it’s just a random “Made in Korea” spoon, use it for stirring your coffee or donate it to a thrift store.
Don’t get scammed by people telling you it’s “vintage silver” and worth a fortune. And for the love of all that is holy, don’t try to melt them down unless you enjoy setting money on fire.
Now go use that spoon to eat some ice cream. You earned it. And if anyone asks, just tell them you’re eating with “heirloom quality” flatware. They don’t need to know it’s plated.
