As a child growing up in foster care, Doogie Sandtiger never learned to tie his shoes. Today, he is the Guinness World Record holder for most Crocs-- a goal he put into motion years ago and proudly achieved by showing Lisa his more than 3500 pairs. This Croc-star's eye-popping collection includes high end collaborations with famous artists, to a finger-lickin'-good collab with everyone's favorite chicken franchise. There's even a special pair he wore to be in his brother's wedding. Today, our Croc-solid toy expert, John Ragusa, steps into his role of appraiser and expert, by putting a dollar amount to Doogie's collection and then, by offering a Crocs trade. John hopes his trade item--a combination between a toy and Croc, will convince Doogie to swap some of his Crocs, while our collector hopes he won't "Croc" under the pressure.

Ashley Sero grew up in a doll house. Literally, surrounded by the vast number her mother Patty had collected over several years. As Ashley - and her love for the collection -- grew, she wanted to start one of her own. She decided to begin with Skipper, Barbie's younger sister. More than two decades later, Ashley has a wide-ranging doll collection numbering in the hundreds, and she walks Lisa through it all. As she expanded the scope of her prized possessions, Ashley decided to share her passion for and knowledge of doll collecting with others, launching her own YouTube channel, Confessions of a Doll Collector's Daughter, which has attracted scores of avid fellow collectors. Ashley takes personal property appraiser and fellow doll aficionado Kate Martin through some of her more unique items, including extremely rare Japanese Skipper dolls. Kate appraises Ashley's collection, before offering a tempting trade - a beautifully preserved iconic figure from Switzerland for one of Ashley's long treasured, and with good reason, staple items.

John appraises Shawn's collection and attempts a trade - offering an ultra-rare set and display featured in a Montgomery Ward catalogue in exchange for a dispenser from the 1984 Winter Olympics.
