So I bought a handful of "new and genuine" coins off ebay the other day, today they arrived but look fake to me - the colour is different (more yellowish), the Lego logo is bigger when compared to my definitely original coins, and the numbers on the flip side don't stand out as much as on the originals, the embossing is very light and not as pronounced. Maybe those were produced later on (the ones I have are from the 90s wave)? Can someone help? Here's a pic with 2 of my coins on top of the ebay ones:
