Frequently asked questions
How quickly will I get a response?
We answer messages within one business day. For order-specific issues, drop your order number in the message and we can get to it faster.
Can I sell my collection to you?
Yes — send photos, quantities, and condition notes through the form and we’ll get back to you with a buy offer or trade-in quote.
Do you take consignment for graded slabs?
We do. Reach out with the cert numbers and we’ll walk you through the consignment terms and our current take rate.
Where can I catch you live?
Daily on Whatnot under @kryptology. DM us on Instagram if you want a heads-up before a specific break.
