Probably not as much as you think. Chances are it was not regularly maintained, so its playing value is probably non-existent. If it is a beautiful piece it might be worth something to somebody. it really depends on the what kind of shape it is in. Tuning an Accordion is a difficult process which can often cost 1,000$ for an overhall, and the chances are the accordion would be worth less than if tuning was invested in the accordion. If it is an average 100 year old accordion you might get 200$ for it on ebay.
Accordions that are 100 years old won't be worth a lot as they will require a lot of repairing and tuning. It will cost you a lot of money to repair it so you would be better off keeping it. If you can play this accordion, then it might worth something but if not it's not worth your while trying to sell it.
Brobably nothing.
eh, maybe $100? Minus the $1000 possibly needed to be spent to get it back to primo operating condition.
