Due to several complexities collecting and identifying the Enschede issues with varnish under the phosphor strips poses a problem for many people. Dated marginal stamps can help solve this problem as the stamps are catalogued and described in specialist lists.
This week a selection of Enschede dated pairs is now trending on that auction site we all love to hate.
AY, A2Y, A3Y and A2B phosphors are listed. I see a couple with 4 mm varnish but most of them are 2 mm. Blue, cream and white gums are also listed. All of individual pairs in the lots have been identified in the description of the listings which helps to make the Machin collectors life just that little bit easier.
This pic is just one of several lots that are available.
