Version and identification
Check the code printed below the artwork on the right: it should read RA03-EN199. RA03-EN199 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 Junk Synchron: RA03-EN199 Platinum Secret Rare (€4.61). 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 €26.64, a PSA 9 for €132.40 and a PSA 10 for €181.52. Our monthly prices for it go back to November 2024. Over the last 12 months ungraded copies are up 101%, and up 7% in the last month. Its highest monthly ungraded value was €29.94 in January 2026, 11% above today. PSA 10 copies have moved up 64% over the same 12 months.
Grading and population
A PSA 10 sells for 6.8× the ungraded price and 1.4× a PSA 9. That gap is big enough that grading a sharp, well-centred copy can pay for itself. 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: steady demand, with ungraded prices up 101% in a year; an active market (25 recent completed sales), so it is easy to sell. Against it: large modern print runs, which tend to cap prices unless a card becomes iconic. Past prices do not guarantee future ones. This is not financial advice.
Before you buy
Expect to pay around €26.64 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €132.40. Ask the seller to show the code RA03-EN199 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.
