If you check when it was funded you can be certain, some people load their physicals instead of making a new paper wallet or address to save coins. Altho, indeed, you should empty them up if not sold given fame the project has.
Ok, I’ll do some more research about these coins but I think I will empty them up.
Does anyone know why one of the coins was funded twice?
1 of 2 possibilities:
1- The maker double funded it on accident. This has happend over the years by various makers.. some mistakes, some just happend by chance. Even BTCC had a few double funded items!!

2- End user funded the coin themselves using it as a wallet for themselves.
If the fund dates are close, most likely the first one.
