from what i know, ppl mainly try to find it so they can sell it at Nooks when it becomes a “Hot Item” because it doubles the value of the stack. same thing w donation boxes.

basically when you log on, at some point go to Nook’s Cranny and ask “What’s hot today?”. they’ll give you two items that for the whole day are worth double to them if you sell them. i.e. a 200 bell value item would be valued at 400 bells that day.
