Your childhood back
Ordinarily, "collectibles" make terrible investments, if only because a Precious Moments figurine will never have more monetary value than when it's sitting on on a card-store shelf. If you're collecting what you love and doing your homework while doing so, however, a beloved hobby can get lucrative in a hurry. The best example is in comic books, where such obvious choices as the Amazing Fantasy No. 15 that features the origins of Spider-Man sell for $150,000 to $300,000 and Action Comics No. 1 featuring the first appearance of Superman sells for upward of $1.5 million. If you're a big Spider-Man fan from way back, however, an Amazing Spider-Man No. 1 can still be had on eBay for around $3,000, but more intriguing prospects such as Amazing Spider-Man No. 122 (the death of the Green Goblin) or Amazing Spider-Man No. 49 (the first appearance of the Vulture) fetch roughly the same amount.
