Price guide methodology
A useful coin estimate and a useful figure comp do not come from identical evidence. GrailPulse keeps the standard consistent — name the source, preserve collector context, explain the method, and show the limits — while letting each guide use the evidence that fits its market.
Step 01
Figure guides lean on completed public sold comps. Die-cast guides use modeled seed estimates with casting and condition context. CoinSpinner combines published-guide estimates with grade, melt, and source context. The source is identified so you know what kind of number you are reading.
Step 02
A single average hides too much. Grade bands for coins, carded versus loose for die cast, and loose versus sealed for figures keep unlike examples from being blurred into one misleading number.
Step 03
Where sold listings are used, lots, reproductions, customs, damaged listings, mislabeled items, and obvious outliers are filtered. Where guide estimates are used, the guide and relevant qualifiers stay attached.
Step 04
Each product explains its own pricing model, evidence labels, update cadence, and correction path. Thin or incomplete evidence should be identified rather than dressed up as certainty.
The same trust standard, every shelf
A coin’s grade matters the way a figure’s seal does, but their markets do not produce identical data. The method bends to the category without bending the honesty of where a number came from.
