I have just come across this item whilst preparing an extensive estate lot of Tasmania

It has been recess printed, is perf.14 (a dead giveaway) and has a bogus barred numeral cancel
Has anyone seen such an item before? Why would anyone want to forge the 3d value?

Is this item watermarked? If it is unwatermarked, it could be a reprint
that has been supplied with a fake perf 14 and bogus cancellation.

I have seen something like this in the 10/- Dragon.

The 3d St George and Dragon perf 14 may be derived from a reprint on
unwatermarked paper of 1879. This is the case for a 10/- Dragon with
perf 14. This perf only occurs on De La Rue printings. No watermark
at all to be seen! Someone has obviously fiddled with several reprints.
Possibly more may turn up.
