Footy memorabilia '- 18th birthday

My lad turns 18 soon and I'd like to get him something special in the way of footy memorabilia (City, Wales, Bale Madrid etc)

Any recommendations for purchasing from a reputable source please? Would prefer a shop where I can see the 'goods'. Won't consider EBay or any individual seller. There used to be a shop in Chester but seemed to recall the two brothers running it had a bit of trouble with the law taking an interest in the origin of their goods.

Budget £500.

Thanks
