Yup... was pretty sure it did but just tested it out for you on an unused character from scratch to be sure. Just got the " They seem unwilling to give you any money " message until 7.3 begging, when a generous herbalist donated an entire gold piece to the cause. Ginseng sales must have been slow that day....
9.8 begging just got 11gp from a provisioner. So yes its slow to raise etc but probably a fun way for a starter character to get a little bit of start up cash on Siege.
