How we calculate premiums
A price alert is only worth something if the number is right. This is the exact method behind every number we publish — the same method, every time.
Sold prices only
Asking prices are wishes. We only count completed eBay sales — what someone actually paid, never what a seller hopes to get.
Exact-product matching
Same coin, same year, same finish, same packaging. A close cousin is not a comp — mismatched products are the #1 source of wrong premiums, so we're strict, and when a listing is ambiguous we leave it out.
Median, not maximum
We report the median of recent sold prices. One shill bid or one outlier auction can't move our number.
Comp count shown, always
Every premium comes with its evidence: ~$205 (median of 12 solds, last 24h).
If there aren't enough sales to be confident, we label it a "thin read" —
or we stay silent. Silence beats noise.
Sellouts confirmed twice
Product pages flicker and caches lie. We never say "sold out" on a single check — every sellout is confirmed twice, minutes apart, before an alert goes out.
If we ever publish a wrong number, we correct it publicly and fast.
What we are — and aren't
- We report observed prices: what sold, for how much, when.
- We never give buy/sell advice; projections are always labeled as projections, and no sponsor or affiliate ever changes a reported number.
- Every alert links the actual sold listings so you can check us.
