One of the most captivating shows in television history faded to black for the final time last week. After eight seasons and 73 episodes, "A Song of Ice & Fire" reached its conclusion. And while the show may be over for now, until the spin-offs come out, the collectible memorabilia related to the show will hold its value. 

Game of Thrones crossed many cultural boundaries, it became more than just an entertainment show to many. Brands like Oreos made special edition cookies dedicated to the series, breweries like Ommegang made beers named after characters in the show, and don't get me started on the limited edition whiskeys that I spent entirely too much money on! With references in shows like Parks and Recreation and parodies in Bob's Burgers, people who didn't necessarily watch the show themselves, were exposed to it on many fronts and could share basic plot points. 

Given its impact, there is no surprise that it filtered into the hobby. Autographed trading cards, photographs, replica items and posters are hot commodities for collectors. And we expect them to continue to hold their value long after the show is over because it became such a part of American Pop Culture. Very much like Seinfeld, Friends and The Office, Game of Thrones will be relevant and collectible long after it has stopped airing. 

“No other television show has had the impact on collecting that Game of Thrones has had,” said Steve Grad, Principal Authenticator at Beckett Authentication Services. “Its characters will live on long after the show finishes. From Emilia Clarke to Kit Harington, they are some of the most popular and iconic figures in collecting. Fans will always continue to search out their signatures, as well as their castmates.”

Grad, also of “Pawn Stars” fame, has his own extensive collection of “Game of Thrones” autographs. A few are shared here.
