TCGBerg fair value by gradeSide-by-side comparison of value across every grade and ungraded condition we track for this printing. The bar chart uses a log scale so raw and gem-mint fit on one axis. Solid bars are the TCGBerg fair value, modelled from recorded sales. Hatched bars are the latest market price instead, shown for ungraded conditions that trade too rarely for us to price one honestly.
Value at each grade and ungraded condition, on a log scale that spans the full range from the lowest grade at $2.1K up to gem-mint at $25.4K. Log scale. Tap a row to switch the whole page.
