How much is Mudragon of the Swamp (Quarter Century Secret Rare) worth?

Mudragon of the Swamp (Quarter Century Secret Rare) from 25th Anniversary Rarity Collection has a market price of $25.57, last updated Aug 10, 2026. That figure is for a loose, near-mint copy of this exact printing — a played copy sells for less, and a graded one is a different market entirely.

What makes Mudragon of the Swamp (Quarter Century Secret Rare)'s price move?

Three things: how many copies were printed, how much the card is played, and how many people are chasing it this week. Mudragon of the Swamp (Quarter Century Secret Rare) is a Quarter Century Secret Rare from 25th Anniversary Rarity Collection, so its supply was fixed when the set was printed and only demand can move it after that.

Where does this price come from?

It is the TCGplayer market price: an average of what copies of this printing have actually sold for, refreshed daily, in US dollars. It is not a shop's asking price and not the cheapest listing, which is why it tends to sit below the buy-it-now prices you see. CardFrame does not publish graded (PSA, BGS, CGC) values or euro pricing for Yu-Gi-Oh cards — one honest number per printing is what the data supports.
