The phones are not especially valuable here in the USA, but they are certainly worth more than $10. Such phones on ebay might sell for $20-$40, and perhaps more on a good day. The cut-away finger wheel should add at least several dollars to the value, but a frequency ringer will decrease the value somewhat. Pictures of the outsides and insides of the phones would be good. Chances are that someone on the forum would be interested in the phones. The dial parts might also be useful to forum members.
