  • Although the vouchers' weight is shown as one, being "quest items" they are actually weightless. This also means they cannot be dropped normally and must be spent at the Prize Redemption Terminal or removed through console commands.
  • This item exists in Fallout: New Vegas, albeit only as legacy content.
