Your first question is, "What is a Big Hug Mug?" It is an oversized ceramic coffee mug used by Matthew McConaughey's character in the HBO TV show, "True Detective." The mug was used by FTD florists in a specific arrangement that also came with a stuffed bear. Producers of the show say there is no real significance to the mug. It simply adds a splash of levity to the set since the show is so serious. But the mug has quite a following and fans of the show are willing to pay top dollar on eBay.
As of this writing, the best sale on eBay of a used Big Hug Mug was on March 9 for $118 with free shipping. There are some copycat mugs being sold also. The original Big Hugs are a cream color and the reproductions are white. There are less than 50 Big Hug Mugs for sale on eBay at this time. Most are on auction so the market will determine the price. Completed listings show 123 sold mugs - that includes the reproductions.
