Well, I have now completed my plate block inventory up to 1980. I think the plate block collection I bought only goes through 1996, so I am getting close. Of course, the Shekel definitive issue from 1980 is going to take a while. Not only are there 98 different dates, but the Definitive specialized catalog had a special supplement for this issue. There are about 400 varieties of plate blocks, and I know I have at least half. So, it will take me a while to make it through this issue.
One more update on the Telabul draw your own stamp. I see someone is very optimistic on E-bay, offering a full sheet (20 stamps, 3 with tabs, plus the central label) for $2000. While this is a rare issue, I don't think the price is justified. I would rather buy J1-5 tabs for that price.
