300 Pieces of Silver

 is an unmarked quest in Fallout 3.

If you tell Moriarty you don't have 100 caps to buy information on your father, he will give you a cap raising task. He wants you to find a woman called Silver and get his money back. You can find Silver north-west of Megaton at Springvale, inside a ranch house.

Solutions and rewards
You can go about this situation one of six ways:
 * 1) You can kill her and obtain 400 caps along with her equipment with NO karma change unless you start taking stuff from around the shack. She will attack you straight away if you say that you are there for the caps.
 * 2) With a successful Speech attempt you can convince her to give you 400 caps to tell Moriarty she's gone.
 * 3) You can convince her to give you 300 caps to tell Moriarty she's gone.
 * 4) You can ask for no money and tell him she's gone this will result in positive karma, though you are still going to have to come up with 100 or 300 caps.
 * 5) You can simply say she's gone without working out a deal with her, though again, you will still have to come up with the money on your own.
 * 6) With the speech check you can make her give you 400 caps. You can then kill her to loot another 100 caps from her body.

Bugs

 * Do not agree to tell Moriarty she is gone before talking to Moriarty, or he may spawn into an inaccessible area; see his own article for tips on fixing the problem on the PC version (console players cannot fix the problem).
 * Completing the Megaton part of Following in His Footsteps will also remove the possibility of completing this quest (even if you talk to Silver first about it).
 * If you talk to Madison Li about your dad before completing this quest, all quest dialogue with either Moriaty or Silver will disappear and Silver will offer only post-quest dialogue.
 * Both times I've played a new character on the PS3 version, I talk to her, get the caps, and when I talk to Moriarty I am not given the chance to tell him that she's gone, or get the quest to get his money back. This has happened on the XBOX 360 version as well, Silver is in fact never mentioned in the conversation with Moriarty if you speak to her early, even though you say you are receiving the caps for Moriarty.
 * the bug with silver and the caps for the ps3 also activates if you kill her and take the money before you talk to Moriarty. You're not given the quest. a bug?
