Scouting
Sports card scouting
Everything we publish here starts with the same question collectors ask us inside the Valdar app: what is this card actually worth, and what should I do with it? The answers in most search results are either a price-guide paywall or a list recycled from the same three sources. We write the version we wanted to read — built on real eBay sold listings, public auction records, and the grading population data that actually moves prices.
Valdar is a card scanner: point your camera at a card and it identifies the player, set and parallel, then shows you what that exact card has been selling for. Working on that engine means we spend our days inside sold-comps data — watching which 1980s Topps cards actually clear four figures, how much a PSA 10 premium really is over a raw copy, and which "valuable" cards from the junk-wax era still trade for a dollar. These guides are where we write that perspective down.
What you'll find here: value guides for the sets and players people search for most — with honest numbers, not wishful thinking; grading explainers that tell you what PSA, BGS and SGC actually charge and when grading is worth the fee; and market research on where card prices are moving. Every price we quote is framed the way we'd want it framed as buyers: recent sold ranges, not decade-old book values and not asking prices that never clear.
If a card is sitting in front of you right now and you just want the number, the fastest route is the scanner itself — free on iPhone and Android. If you want to understand the market before you buy, sell or submit to grading, start with any report below, and when you reach a decision that needs arithmetic, every report hands you the calculator that does it.
How these are written
Every report here follows the same three rules, and they are worth stating because they are what makes the difference between a scouting report and a rewrite of the same ten sources.
A number appears with its source in the same sentence. Where a figure comes from a grading company’s published scale, the company and the date it was read are next to it; where it comes from a government series, the series identifier is next to it. Reference values across this site were read on 2026-09-11, and the 8 primary sources are listed on the open data page with the URL of each.
Anything that moves is not written down as a fact. Grading fees, marketplace percentages and postage change quarterly, so no article on this site quotes one. They appear only as fields you fill in on the calculators, with a link to the publisher beside them. An article that quoted a fee schedule would be wrong within a quarter and would still read as authoritative, which is the worst combination available.
The decision is arithmetic, and the arithmetic is published. Where a report reaches a point that turns on a calculation — whether grading pays, what centering permits, what a population report actually says — it hands the reader the tool rather than a rule of thumb. There is one copy of that arithmetic on the site, and the browser tools, the public API and the machine endpoints all run it.
What the reports cover, and what the tools do with it
The twelve pieces below split into three groups. Four are about grading — what the companies actually charge, what their scales actually say, and when submitting is worth the fee. Five are about value: which cards from a given set or era carry money and which do not, written against sold data rather than book values. Three are about specific families of card that people search for by name. Between them they route to 16 of the 24 calculators.

How to read a value claim, anywhere
Most of what is written about card values fails one of four tests, and the tests take seconds. They are worth applying to this site as much as to any other.
Is it a sold price or an asking price? An unsold listing at four figures tells you that one person would like four figures. Only completed sales are evidence, and the distinction is the single largest source of wrong numbers in this hobby.
Is it one sale or a sample? A record price is a fact about one transaction between two specific people, and quoting it as the value of the card is like quoting a lottery win as the value of a ticket. The useful figure is the middle of a sample, with a range around it that says how wide the uncertainty is.
Does it say which grade? On many cards the top grade sells for several times the grade below it, so a price quoted without a grade describes no object at all. A figure that moves by a factor depending on a detail the writer did not mention is not a figure.
Does it carry a date? Card prices move, sometimes by half in a year. A number without a date is an assertion about an unspecified past. Every figure in this section carries one, and where it comes from a source that revises, the source and the date it was read are printed beside it.
What we do not publish
There is no price list on this site, and there will not be one. A price list is a number for somebody else’s copy of a card on a date the reader cannot see, and the honest version of that answer is a calculation performed on sold data the reader has in front of them. There is also no grading fee anywhere in this section, for the reason above, and no ranking of the grading companies by quality — what is published about them is 5 sets of verifiable facts and 3 published scales, with a tool that lets a reader weight what they care about and shows every contribution to the result.
| Era | Years | What a common card from it is worth |
|---|---|---|
| Tobacco and caramel era | 1886–1941 | Even a common card from this period is a survivor. |
| Post-war vintage | 1948–1972 | Commons hold a small but real value, and high-number series printed late in the season are scarcer than the rest of their own set. |
| Late vintage | 1973–1980 | Production climbed but distribution was still seasonal and regional. |
| The competition years | 1981–1986 | Donruss and Fleer broke the Topps monopoly in 1981 and production rose sharply. |
| Junk wax era | 1987–1994 | This is the period that taught a generation that cards are worthless. |
| Insert and parallel era | 1995–2000 | Print runs collapsed after the 1994 strike and manufacturers moved value into inserts. |
| Autograph and memorabilia era | 2001–2008 | Base cards are filler by design; the product is sold on the guaranteed hit in the box. |
| Exclusive licence era | 2009–2020 | One manufacturer per league meant fewer sets and much tighter control of supply, which is why base cards from this period hold more than junk-wax base cards ever will. |
| Modern era | 2021–2030 | A boom, a correction, and a licensing reshuffle. |
The full era table, with what does carry value in each period and the grading outlook, is in the era checker and as open JSON.
| Test | Fails when | What to do instead |
|---|---|---|
| Sold or asking? | The figure comes from a live listing | Use completed sales only |
| One sale or a sample? | A record price is quoted as the value | Take the middle of a sample, with a range |
| Which grade? | No grade is stated on a card whose grades differ by a multiple | Price each grade separately |
| What date? | No date appears anywhere near the number | Treat an undated figure as unusable |
The value calculator applies the first three by construction, and prints the fourth as a recency weighting you can switch on.
Corrections
Everything here is transcription plus arithmetic, and both can be wrong. If a figure does not match the source it cites, or a source has moved, say so — corrections are made and credited. Reports are written by Merey Tleugazin, who builds the card-scanning app this site publishes and is not a grader, a dealer or a certified appraiser; the authority here is meant to come from showing the working and citing the primary source, not from a credential.
