As mentioned (and documented) on here more than once (and in black and white, no less), the ND jetons are only available as photos with a watermark so can't (and shouldn't) be added to the guide which is why only the details are there. They were found online in 2014 so obviously the sizes are not known and if they were then they would be there. They have been listed so that it is known that they exist (and are not Portsmouth ones as implied not long ago) and there are many more instances of the same type of thing being done on the guide so it's not unusual.
Just for future reference the guide admin has seen the photos so they know they exist and although they look exactly the same as the ones recently bought on ebay, the size can't be confirmed for sure (although I expect that they are the same size and construction). There are 3 distinctly different types/sizes and the ones listed should be the same as the ones that are similar. The pink one is not hot pink (or it would have said so) and looks the same as the one that may be added to the guide someday soon, although hopefully the photo will be better than the one recently added at long last. When any others are added I'm sure that the admin will use his knowledge, experience and common sense in deciding whether to update the existing listing or add another but that is entirely up to them and nobody else (or so I've been told). If they need to see the photos of the pink one again to compare then I am happy to send them it again but I'm pretty sure they will be able to tell without seeing it again. Hopefully that clears up any confusion that has arisen from not understanding why they are there without photos or sizes (although it was explained more than once, a while ago). Now we just need to find another 11,780 more and we'll be cooking on gas!
