Not every card gets to be so valuable that people are eager to find it. Some cards have their place in the game. They can still be found in the second-hand market, but you have to dig and scan for it and if you are determined, then you can find it, and some of them can be valuable.
Doomcaliber Knight – $700
Doomcaliber is one of the cards that has a fair price. It is from the 2006 Shonen Jump Championship. It was only awarded to the first three winners. You can still find the versions of the card online, but you have to know what you are looking for as the card has been published several times. If you can get your hands on any card that has GLD4-EN02 code, then you should rest assured that it surely is a good catch.
Chinese Dark Magician – $1,050
The card dates back to 1999 when only 100 copies were produced. Even though the card has been published in various languages, the Chinese one is what is valuable and you should always keep that in mind. Priced at $1,050, the card came out as conjunction with Weekly Shonen Jump magazine.
Dark Magician Girl – $1,100
Dark Magician Girl is priced at $1,100. This is a Japanese promo version that was given to tournament winners and participants in 1999.
Shrink – $1,200
You can find this card online and you can get it for a cheaper price but that’s not the actual thing that you have to get. The first edition ones are really valuable and the price can mount up to $1200. It was released in 2006 for Shonen Jump Championships winners. In extreme cases, the price can go up to $7000. You will need extra knowledge to determine whether you have a first-edition or not and once you have it, it can be really valuable.
Gold Sarcophagus – $1,372
Gold Sarcophagus is a valuable card. Only 20 copies of this card were produced from 2005 to 2006. This is what makes it rare. These were awarded to the winners of two Yu-Gi-Oh! Championships. There were also additional copies released. If you want to find the correct version of the card, look for SJC-EN002 code, and get the card that has put this down exclusively.
Des Volstgalph – $1,530
This is one of the rarest cards available in the market as only 20 copies were ever produced in 2005 during the Pharaoh tour. It has G6-01. The code sets it apart from the others. In extreme cases, this card can sell for $2000.
Minerva, The Exalted Lightsworn – $1,900
The card was released in 2015 and is a super rare card. It has quite a high price in the market and can even sell for $2800.
Conclusion:
There can be a difference in prices, but if you can get your hands on the limited-edition, that type of cards can be sold for more than the expected price. You will also need to know what exactly you have to find.
