1999 UK 1st Edition Topps Factory Sealed Boxes

I’m being offered these boxes in trade for a card I have.

I have no clue about them, what are they? What’s the conservative value of each box?

Thank you for your help!


Topps series One box. Bulbapedia link will provide you with a detailed overview of the set (link above). Ebay sold listings should give you a round about mark on their current market value.
Best of luck :wink:
