Enter a certification number to jump straight to that grader's own official verification page — this app never scrapes or stores grader data, it only opens the real lookup for you to check yourself. Always compare the returned grade, subject, and photo against the physical slab before paying.

Ask Claude, grounded in a live web search, what's trending or valuable to source right now — across your categories, or a specific one.

Track what you've actually bought and sold — real profit, and how close the estimates come to reality. Use "📦 Mark as bought" on any listing card, or add one manually below for off-platform purchases.

Add sales from the last 180 days. Three or more closely matched sales automatically replace active asking prices in the opportunity valuation.

Search each marketplace directly or import its current listings. Imported prices are immediately checked against your recent sold comps using the same cost and risk model.
