About Armory Arm
Armory Arm is a Synchro Monster, summoned from the Extra Deck with a Tuner and other monsters whose Levels add up to its own, printed as RA03-EN213 in Quarter Century Bonanza (2024) as a Quarter Century Secret Rare. It is a Level 4 LIGHT Machine monster with 1,800 ATK and 1,200 DEF. Quarter Century Bonanza, released in late 2024, mixes classic cards from the original series with modern staples, each in several rarities including Quarter Century Secret Rare and Platinum Secret Rare. Ungraded, this printing ranks 80th of the 968 Quarter Century Bonanza cards we track. The top card is Blue-Eyes White Dragon at €192.99.
Character and collecting appeal
Machines range from early robots to modern archetypes, and the Type has a loyal following. In play, it is a card for Special Summoning, destroying cards and dealing damage.
Version and identification
Check the code printed below the artwork on the right: it should read RA03-EN213. RA03-EN213 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 Armory Arm: RA03-EN213 Platinum Secret Rare (€12.80). 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 €22.25, a PSA 9 for €99.75 and a PSA 10 for €143.16. Our monthly prices for it go back to November 2024. Over the last 12 months ungraded copies are up 425%, and flat in the last month. It is trading at or near its highest recorded value. PSA 10 copies have moved up 167% over the same 12 months.
Grading and population
A PSA 10 sells for 6.4× 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. Even pack-fresh modern cards can have surface scratches or curling foil, so a 10 is never guaranteed.
Investment potential
In its favour: steady demand, with ungraded prices up 425% 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. Card prices can fall as well as rise, so this is not financial advice.
Before you buy
Expect to pay around €22.25 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €99.75. Ask the seller to show the code RA03-EN213 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.
