Version and identification
Check the code printed below the artwork on the right: it should read RA03-EN145. RA03-EN145 is the English printing. Other languages use their own letters in place of EN, such as DE or FR, and are priced separately. It is the Quarter Century Secret Rare version. Quarter Century Secret Rares were introduced for the game's 25th anniversary. Quarter Century Bonanza has one other printing of Machine Duplication: RA03-EN145 Platinum Secret Rare (€2.22). Each has its own price, so match the code, edition and rarity exactly.
Price history
Today an ungraded copy of this printing sells for about €5.70, a PSA 9 for €28.02 and a PSA 10 for €59.52. Our monthly prices for it go back to November 2024. Over the last 12 months ungraded copies are down 47%, and down 3% in the last month. Its highest monthly ungraded value was €10.71 in April 2025, 47% above today. PSA 10 copies have moved down 29% over the same 12 months.
Grading and population
A PSA 10 sells for 10.4× the ungraded price and 2.1× a PSA 9. That gap is small, so grading fees may outweigh the gain unless the card is for your own collection. Modern foils can leave the pack with scratches, print lines or a slight curl, so even fresh copies do not always reach a 10.
Investment potential
In its favour: a price well below its April 2025 peak, which some collectors see as room to recover; an active market (25 recent completed sales), so it is easy to sell. Against it: falling prices, down 47% in a year; large modern print runs, which tend to cap prices unless a card becomes iconic. Treat this as background, not a prediction or financial advice.
Before you buy
Expect to pay around €5.70 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €28.02. Ask the seller to show the code RA03-EN145 and the Quarter Century Secret Rare finish clearly in the photos, as listing titles often mix up printings. Modern foils can be scratched or curled straight from the pack, so check the surface under a light if you plan to grade.
