Take a careful look, Phil. There is no such
gap above the keys on a Roland stage piano through
which a coin could pass.


** The keys move, so there is a gap enough for a small coin.

Take a look at a Roland stage piano, and then at the
thickness of the thrupenny bit. The keys pivot at the
back, so even though the front edge of the key drops
by 10mm, the rear of the key and the very narrow gap
between it and the case, does not increase enough to
allow a coin to enter.

Furthermore the horizontal space, even between the
E and F keys and B and C keys which have no black
keys between them, is certainly not wide enough for a
thrupenny bit.
