What kind of coins are these?

its called a dd bust but i dont know what its on because this design was on the half cent, cent, dime, quarter, half dollar, and dollar... someone with more experience with it could prolly tell ya what it is with dimensions or just by the pics.... i THINK it is a dollar because it has many of the aspects from different dies that they had. for instance the numbers "1800" looks like it is from two different dies, and "18" and "00" are seperate. they call it the "low 8" there are like 20 different combinations of those dies cuz there was a bunch of different ones. they are worth like $500.
