Perhaps you should do some research yourself if you are planning on buying them? Instead of making those of us who have done the research do it for you. Just saying... I'm all for helping out when someone wants to learn. But if your whole goal here is to profit of others' knowledge, you can count me out. Good luck.
The following sites have comprehensive lists of known doubled dies www.doubleddie.com www.varietyvista.com They are really good to bookmark. Generally, when somebody asks about a doubled die, if it's not an obvious MD or DDD, many members will use these sites to help confirm. It shouldn't take too long to look up possible doubled dies on there. In addition, doubleddie.com has a section called worthless doubling which gives a good explanation of Mechanical and die deterioration doubling. Instead of asking "Is this a doubled die?", a better question would be "is this coin DD0-00X listed on doubleddie.com" or "I couldn't find any DDOs that match this coin on Varietyvista.com". That way, people won't feel you're taking advantage of their time and knowledge and you'll learn a lot by looking at examples of true hub doubling.
Except he straight up said he doesn't "have the time to research". He would rather take advantage of the members here while putting minimal/no effort in himself.
