Lighthouses

There are a lot of groups of collectors of special stamps or postcards. One nice group is the Lighthousepostcard group. Also for collectors of that kind of stamps. Here you see a lighthouse personal stamp. Isle of Texel in The Netherlands. Only 10 pcs made, so this is a very rare stamp. This kind of personal stamp you cannot order anymore. Its the 2007 version and, indeed we have 2008 now.

What is the value of an issue of 10 stamps, you may tell me.
