PC Hornbow

Hey, I was wondering if this was worth anything since I nor have a couple others I've asked seen this damage multiplier before in-game

Its a relatively uncommon damage Mod. You can find them in these forums if you search for "Dual Vamp". They are used for suiciding faster for example.

2 Handed ones are not too sought after (Not that it should really matter as they want to die anyways), so Id guess at around 10-15K for that bow.

Dual vamp weps are very nice, but only if they are one-handed. Yours should be some 10-20k, depending on skin (there are several hornbow skins). If it is a mursaat skin, then a little more, but not overly - some 30-40k imo. Get more opinions.
