Dear Spiro, To be honest, as singles or small parts of the sheets of 12 that were issued, these Congress labels are not valuable and they are not rare items. If you check them out on
ebay, you will often see similar pieces offered; the damage that this strip has suffered will not help the commercial interest. They were issued in a set of four different coloured sheets so I usually try to acquire the full sheet set when I buy them. Chris Wren
