A hoard in D.C. featuring Kobe Bryant and Michael Jordan memorabilia might be swallowed up by mold. The three-story home is so packed, the front door won't open. Matt hunts for a serviceman's foreign currency collection. Extensive repairs drive up costs.

Matt's team goes full hazmat suit to tackle a rat-infested hoard that is rumored to have cash hidden in every room -- if the rats haven't eaten it already. The team also hunts for vintage Playboys, a rare samurai sword and original G.I. Joe toys.
