Information is a slithery concept, 'information-bearer' possibly even more so.
In this paper I will discuss various ways in which ancient coins serve as
historical information-bearers and generate (mainly but not solely through
hoards) emergent information. We will see how this information may be
'virtualized' through computer applications and what the possible advantages
of this are. I will present a few existing online databases and other facilities
that are useful for numismatic research and suggest how these facilities may
be improved and complemented.
