Shiki didn't say Roger had them, but he said that Roger knows their location And as long as it's not in One Piece, Luffy doesn't need it and the Gorosei don't have the ancien t weapons, because their locations are written on Poneglyphs, meaning that the ones who created the Poneglyphs also built the ancient weapons to destroy their enemies(that won the war and became the WG, so there's no way there could be one in the WG's hands) and the ones with the D have some connection with it.
