An auction was held recently in Sydney, Australia, where an Ampico and a
number of Ampico rolls were part of the offering.  Prior to the auction
an article appeared in the Sydney Morning Herald, which suggested the
Ampico would sell for $100,000.  A 1923 5'4" instrument, it had a
painted case and played reasonably well.

As it turned out, bidding reached $27,000, but the instrument was
passed.  I don't know what the reserve price was.  The rolls were
offered separately, and I understand some were sold.  It seems auctions
bring the best(?) prices!
