Bubbles
Bubbles was introduced in 1995, and his value has skyrocketed since. Abundant with manufacturing abnormalities, this famous fish is worth a fortune if you can spot them. The third-generation doll's mouth has mismatched thread, while fourth-generation Bubbles has spelling errors on his tush tag.
With errors such as numerically written birthdays and limited edition hang tags, these expensive aquatic creatures have sold for $130,000, with even non-error editions selling for around $20,000.
