I am taking the easy way out - shoewreckys link to those websites is the place to go. there are so many little things that can be looked for that I think the list of wheatie years that doesn't have an DDO RPM OMM so forth and so on is much smaller. Actually thats a good question. What year/mm's are there not any varieties that are included in top 100 lists?
all this talk of world coins got me thinking so i went and had a look through my local guys "bargin bin" where anything that he doesnt think he can make a big profit off he puts in for 20p. what did i pull out? wheaties lol five of them including a 1916 and '43 steely. and since i buy a lot from there he gave me them for 40p. they will fit right in with my collection of american coins that i dont actually collect lol
