Are you sure it is ductile and not a series of discrete microfractures? The
end result would look the same, have you examined it under the microscope at
high power?
If this isn't the case are you sure it's not a relict, ie: formed before the
coal was lithified?
Hope this helps, sorry if you've already ruled out these possibilities.
