Skip-It
Average original price: $12.89
Potential earnings: $120
Skip-It immediately got the attention of kids after a successful screening advertisement in schools in Illinois. Children immediately made their way to local stores to buy these new toys as soon as possible. Back in the day, you could get the Skip-It toy for only $12.89. Now, the seller could receive a whopping $120 for this toy in its original box. Too bad children these days are mainly excited about getting a new iPhone or iPad.
