Market Opportunity
With the sports card market valued at over $12 billion and eBay reporting sustained double-digit growth, collectors and investors have more at stake than ever. Expert guidance makes the difference between a average sale and a record-breaking one.
Why CardPeak
We don't buy collections. We make yours worth more.
Independent, not a buyer
We never buy collections outright. Our incentive is aligned with yours: maximize your sale price, not our margin.
Platform expertise
Deep experience across eBay, PWCC, Goldin, and heritage auctions — we match your cards to the right venue.
Personalized recommendations
No cookie-cutter advice. Every collection is different, and our recommendations reflect your goals, timeline, and risk tolerance.
No gatekeeping
The free guide, the blog reads, and the eBay store are all open access. We do not put paid advisory between you and an answer.
Authentic eBay feedback
Feedback straight from the founder's eBay buyers.
Every entry below is a buyer's feedback left on the founder's eBay profile — not a CardPeak customer story. Click through to see the full profile, the item-level ratings, and every prior transaction.
The feedback entries are being curated from the founder's eBay profile and will appear here once published.
In the meantime, the live profile is the source of record — every rating, every buyer handle, and every transaction date.

In practice
