Received an offer for Model 1019 Milligaus

[Ruth Biggs]

I've received an offer of $12,000 for my uncle's Oyster Perpetual Model 1019 from about 1962. Does this seem reasonable? It was appraised at $25-30,000. But the argument is that the appraisal value isn't really the value one can get. Just like insurance value isn't the value you can get for selling it. Don't want to let it go too cheaply. Thanks. :)
