Know this is going sound really stupid but ........
I have been checking a few of my heads ready to list and i keep on coming across ones which i dont know if they are fake!! I cannot see the Lego logo on them - they are mostly the series heads. When i check them they are all recessed stud and not the safety studs. Do i take it the ones i have are fake - i do not want to put them up for sale if they are not genuine!!
Comments
Some heads that where made in 'safety' version at first, did re appear in newer issues of the same fig (chicken guy for example) with 'recessed solid stud' (with the LEGO logo offcourse)
Cheers, Eric
If you're ever in doubt feel free to post pictures here, most people will be happy to give them a look :-)
As Robertnat noted, there are minifigure heads that have a recessed stud that at the bottom of the recess have an X. There's no room for the LEGO logo on those, so you can't go by that to determine legitimacy. :-(
The yellow is not quite right and the plastic feels lighter.
Recessed stud is a different mather, as indeed they have been produced a lot in China (rented factory 'till 2016, so TLG did not have full control), with the potential those factories also produced fakes (as they did have the 'print' in stock), the difference is that those heads have the LEGO logo, while the fakes didn't.
Now BL's (and BO is worse I'm afraid) timeline isn't 100% full proof when it comes down to safety stud and recessed solid stud.
2 reasons:
BL does not support alternate heads in minifigs (so even when encountered and added to catalog, they won't show up as being 'known')
TLG: they never throw away parts... Let's assume they produced 75000 medium stone gray heads, they print 7 different prints (when needed) and put them in 10000 sets each. The box will now contain 5000 unprinted heads. They switch mold. Decide to use Medium Stone gray heads in 3 more sets they produce in 10000 sets each... Oops, not enough in stock, we need to produce another 50000 to have enough stock and a bit extra. Then they print, while grabbing the ones 'on top' of the 5000 that are sitting in the bottom of that box of 55000 heads. Result, 2, 3 years later you can still find freshly printed heads of the 'old' mold (whenever they decide to increase the production of a certain set). Obviously the opposite is more frequent during the transitions years, I don't expect 'safety stud' to be found anymore nowadays in newly released sets.
Bottomline, I think you can be quite 'safe' when listing them as being the real deal ;-)
