Well we were forewarned that with all the market activity due with all the new security SA issues / A postage rate rise in April, Prestige Booklets x 4 and design Classic retail booklets x 3 in the pipe line, 2009 may be a very expensive time for the Machin collector.
If you collect cylinder / date blocks this will drain your bank balance even more so. Dave Arthur has posted some information from Royal Mail on the choice formats of the cylinder markings that will be available to the collector.
If you have a bottomless pit of money, this will not be a problem for you, but for the average Mr and Mrs Joe Soap - Collector you may have to make some serious decisions on your future collecting habits.
I myself do not collect self adhesives so I have saved a fortune by drawing a line under these when I did. I expect in this year of 2009 that a lot of Machin collectors will follow in my footsteps.
I could have this wrong so I advise you to go to his post and decide for yourself. Confusingly, looking at his scans it seems that several different cylinder formats will be offered from several panes from the original primary sheet. Now that is what I would call EXPENSIVE !!!
Apparently they (the sheet markings )will be explained in the "February Preview" which Larry (and many others) are waiting for with great anticipation.
