After Roberts revelation about the stamp from the NAFAS booklet with the missing Letter A. Dave Feeney wrote to me and provided a list of all the security stamps (known to him) issued during 2009 with phosphor errors.
He informed me that he has not actually seen these stamps, but got the information from a well known online specialist catalogue.
For your information here are the stamps (complete with catalogue prices) to look out for. I have used the Deegam Sin System to identify the errors. Many thanks go to Douglas Myall for continued permission to use his copyright sin system on site.

Have you checked your 2009 stock yet? Good hunting, do not forget to check the other numerical sheet and later issues including the Prestige booklet pane. It will be interesting to see how many more (if any) phosphor errors are reported from the 2010 sheets and booklet printings .
