This is an authenticated item of the Pokémon Game Boy Red version! First of all, it's quite rare for a Game Boy game from this era to be in this condition! The 87-point rating for the first-generation game software is in very good condition and is recommended! I think it's worth buying this for investment purposes! There is demand from overseas collectors, and I don't know how much it will be worth in a few years! Although Pokémon cards are currently attracting attention, I think it's also interesting to invest in game software! Esports Grading (ESG) is the world's first NFT grading company.
