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.
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.
H owned one year ago and I paid £75, I saw one recently for $75 but that was too low, i was tempted to buy it myself at that price.
1949 - 1972
Research has suggested that the Hohner Harmonica was first made by hand in 1857 and a total of 650 were made in the first year. In the 1920's Hohner began manufacturing harmonicas that could be played in any key.
1930´s
eh, maybe $100? Minus the $1000 possibly needed to be spent to get it back to primo operating condition.
Ebay shows a wide range in price for excelsior accordions sold this year. Age matters but the model number is a big factor. A three year old Continental model sold for $3,000. A model 64084 sold for $42, a model 310 sold for $500.
