How We Make Offers on Collections

Estimated offers often fall around ~75% for individual cards valued over $250, ~60% for raw Near Mint English singles over $5, ~30% for singles $1-5, and ~50% for sealed product. Cards under $1 are considered bulk and purchased at bulk rates. These ranges reflect typical secondary-market expectations and are not tied to Card Kingdom’s internal pricing or algorithms. Offers may vary based on condition, demand, collection makeup, and processing considerations. Slabbed, serialized, and other exceptional items may be evaluated separately.

Our buyers are happy to provide an initial estimate based on the information shared, but the official offer will be made after the collection is received and evaluated in hand. We'll keep you updated throughout the process and confirm when it's received, when we start evaluating, and when your offer is finalized.
