Here's my offering for No 18 | Currency; Coinage or Paper (the odd, the different, the beautiful). This is a nine shilling note, very similar to the 10 shilling note that was legal tender until 1971 except that the ten has been changed to nine. The legal note was known colloquially as a ten bob note. This nine shilling, or nine bob, note, never existed as legal tender and this particular one (only printed on one side) is a take on the phrase "as much use as a nine bob note" meaning a waste of time and/or useless!

Many thanks to Mary-Lou who is organising the hunt and who will list all the other participants on her blog.
