Konami - 6000 Bulk cards - Yu-Gi-Oh!

After years of collecting (about 10–15 years) I am selling my full card collection. In total it comprises around 6,000 cards.

The collection contains a mix of cards that have been used over the years and supplemented with occasional purchases. The condition varies from:
• Poor / Played
• Lightly Played
• Near Mint (NM)

Additionally, there are also many sleeves included:
• Both used sleeves
• And new, unopened packs

Because I’m quitting this hobby, I’m looking for someone who can still derive pleasure from it. The exact value of the collection is unknown, so I’m open to a reasonable offer.
