Licensed means licensed
A club mark on jewelry is either licensed or it is counterfeit; there is no middle ground, and the difference shows in the making. A licensed piece is cut and enamelled in solid metal to a specification the club signed off; the alternative is a printed decal on plated brass that lifts at the edge within a season. Everything on this page is the former.
What survives a game day
Stainless steel and sterling both take a knock better than plated anything. If the piece is going to a stadium in November, stainless is the honest recommendation.
