Holofoil stamp

A holofoil stamp or security stamp is a small holofoil sticker in the bottom center of Magic: The Gathering rares, mythic rares, and promotional cards.
==Description==
===Silver oval===
Silver oval holofoil stamps were introduced in the Magic 2015 set. This was done to make those cards feel more special, as well as to guarantee authenticity. As such, it makes counterfeiting more difficult. Commons, uncommon cards, and basic lands usually do not feature this security stamp, except for basic lands from Unstable.
===Gold oval===
Cards from the Amonkhet Invocations set have a gold holofoil stamp.
===Silver circle===
Cards from the Signature Spellbook sets have circle-shaped holofoil stamps.
===Silver heart===
Cards from Ponies: The Galloping and Ponies: The Galloping 2 have a heart-shaped holofoil stamp.
===Silver triangle===
Non-canon cards feature a triangular holofoil stamp. These were introduced in 2020.
===Silver acorn===
Acorn security stamps were introduced in 2021 for Unfinity, to replace silver borders. On commons and uncommons the acorn stamp is printed on the card rather than embossed.
===Gold "A"===
The first Alchemy cards on MTG Arena featured the MTG Arena "A" as a "foil stamp." This later became a redesigned gold Alchemy "A." The Alchemy stamp represents a digital-only card and is present on all designed-for-digital and rebalanced cards.
