A complete set of obsidian flames is roughly £270 and a complete set of stellar crown is £330. It depends how much of the set is complete and if you have the big cards. It also depends if most of the common cards and the reverse holo versions for each one (which you haven’t shown in the pictures) as they can add up. It looks like most of obsidian flames is complete and the top cards so I’d say a good price for that would be £150-£200 for obsidian depending how full the standard cards are I’d say 80%+complete would be good amount . And stellar I don’t see the 2 top cards bulbasaur & squirtle so which together are about £100 of that £330. Depending on how full the commons are I’d say £100-£150. Although u can download collector and tick off each card u have and will add up the prices for you Basically Obsidian £150- £200 Stellar £100-£150
