A baseball card value guide normally means a list of figures. This one is a method, and the difference is deliberate: figures go stale within weeks and are wrong for any condition but the one they were written for, while the method for reading what buyers actually paid stays true indefinitely.
Why no figures are published here
Any price this site printed would be an assertion about a market it does not observe continuously, for a condition it cannot see, on a date that would soon be in the past. The only measured card-price datasets are held by parties who do not make them generally available, so a figure here would be a guess wearing the clothes of a fact. There are none.
What is published instead
How to identify the exact card, where the sales are, which five to use, and what to do with them. Plus three calculators that do the arithmetic: the sold-comps figure, the real cost of a grading submission, and whether grading a particular card pays. All free, no account, nothing stored.
The method in four lines
Identify the card precisely from its own markings. Filter to completed sales rather than listings. Take five that match your condition. Drop the highest and the lowest and average the rest, then read the spread to see how much those five agreed. That is the whole guide.
When a figure-based guide is still useful
For scanning a large set quickly to find which cards deserve attention. Use it for that, then price the survivors from sales. The two together work better than either alone, and only one of them is free.
Questions people ask about baseball card value guide
Can you just tell me what my card is worth?
No, and not from reticence: this site holds no price data at all. The checker will do the arithmetic on the sales you find in about a minute.
Why is the method better than a figure?
Because it produces a current number for your condition rather than a stale number for somebody else's. It also shows you the spread, which a single figure hides.
Is any of this behind a paywall?
No. There is nothing to buy on this site, no account and no advertising.
Where do the calculators get their numbers?
From you. Nothing you type leaves the page, and the site holds no data of its own.
