Subway token

Subway token is a miscellaneous item in Fallout 4.

Characteristics
The subway token looks to be a small slightly tarnished coin that says on both sides "Boston subway" with a 1.

While previously used to grant civilians access to Pre-War America's many subways, these coins are now do little more than fill the pockets of the bombs' victims. In the Commonwealth however, these coins are seen as an equivalent to caps due to their similar material and negligible weight.

Locations

 * Several are scattered around the cash registers of College Square Station.
 * Can be found randomly in containers, most often in subways, but pretty much every low tier container (i.e. desks and filing cabinets) can contain them as well.
 * Extremely common in the inventory of dead ghouls if looted, as ghouls are prone to spawn several different variants of junk and miscellaneous items.
