“A card that allows the bearer to purchase weapons and items at half price.”
—In-game description, Shin Monshō
The Silver Card (シルバーカード Shirubā kādo) is a card that recurs across the Fire Emblem Series. When held by a character patronising an Armory, a Vendor or a Secret Shop, the Silver Card grants them a hefty discount, allowing them to purchase both weapons and items alike at half their original price. In all the games that the card appears in, only one may be obtained in each play-through, with the SOLE exception of The Blazing Blade, where a second Silver Card may be obtained if one has access to transfer data (this may be in part due to the fact the silver card must be stolen in The Blazing Blade and is unavailable in normal modes except through data transfer, in addition to transfer data being a reward of sorts for players)
In Radiant Dawn, unlike its counterparts in other titles, the Silver Card will promptly disappear after the player exits the base in the chapter that it is received in.
Allows its holder to purchase weapons and items at half their original price.
The Silver Card is procured by initiating a 3 star conversation "Item Shop" in base during Part III Chapter 2. It is valid until you exit the base upon which it disappears. It is not dependant on who is in possesion of the item (It is still effective whilst in the convoy).
Therefore, a good strategy is to sell for 2000g before exiting the base.
