The first Hot Wheels arrived in stores in 1968 and it wasn't long until they became the number one toy. Bruce Pascal was seven years old at the time and remembers the toy immediately becoming popular with his circle of friends.

"It's hard to explain the craze today, but Hot Wheels was huge. All of my friends were saving up to buy all the Hot Wheels they could," Pascal said.

While he was growing up, Pascal, like kids across the country, kept his Hot Wheels in a cigar box. As he grew up, the cigar box gathered more dust, sitting on a shelf for 30 years until Pascal rediscovered the collection in 1999.

"That excited feeling I had as a boy was rekindled instantly," said Pascal. "My friend offered to pay me $200 for the cigar box. I declined and held onto them, but it was his offer that made me start researching the value of Hot Wheels and pursuing collecting as an adult."

His search became a bit obsessive. Pascal began calling other collectors, taking out newspaper ads, and even used a 1969 telephone book of Mattel employees to see if any former workers had rare toys they would be willing to part with for a price. He collected everything he could, including Hot Wheels memorabilia like blueprints, original drawings, sales brochures, and wood models.

His collection grew from that cigar box to thousands of Hot Wheels. Yet Pascal was not satisfied. He still had not found the one Hot Wheels vehicle that was alluding him, the most valuable Volkswagen ever produced - the pink Volkswagen Beach Bomb prototype.

The model was a bit of a folly. When VW and Hot Wheels initially created it, the car's narrow body and surf boards out the back window made the vehicle unable to stay upright when rolled. So, it was redesigned and the sides became more weighted and the surfboards were moved to the sides of the vehicle. This was the model that made it into production. The Beach Bomb was sold with a sticker sheet of flowers to decorate the vehicle, an offering that was very of its time.

The original prototypes with the surfboards out the back window are extremely rare, as only Hot Wheels employees had access to them. Of these prototypes, the pink ones are the rarest of all. There are only two known to be in existence.

"I already had heard about [the Beach Bomb] in purple, green, red, light blue and gold. I even had heard about an unpainted model," said Pascal. "But pink was extremely hard to find. Most Hot Wheels models were marketed to young boys, who the brand assumed didn't want to play with pink. They created just a few pink [Beach Bomb] models to market to their female audience."

Eventually, Pascal networked his way into purchasing both pink Beach Bombs models. He has since sold one of them to another friend and collector, but the one that is in the best condition has stayed with him.

Today, Pascal owns over 4,000 Hot Wheels models and about 3,000 pieces of memorabilia, but the pink Volkswagen Beach Bomb remains his most prized possession.

"I won't say how much I purchased it for," said Pascal, "but it is worth an estimated $150,000 today."

To help prevent sun damage, the Beach Bomb remains in a dark, Plexiglass case. Pascal displays the model in his personal museum in Maryland, where he gives private tours to other Hot Wheels enthusiasts. He has also loaned the model out to other automotive museums and events for display.

"I want other people to experience the Beach Bomb. I've found so much joy in learning about classic cars and Hot Wheels, and I hope I can spark some of that in other people. It's a treasure to find these rare models," Pascal said.
