It is a 'rare' card in that it is a Super Rare from Legend of Blue-Eyes White Dragon, as well as having reprints in other sets.
However it should be considered that there are rarer cards than Super Rares, so it's not 'that' rare in the grand scheme of things.
It all depends on rarity of the card ie. common, rare, super rare etc. and the edition ie. yugi's starter deck, packs etc. I'd say a couple of pounds
