Holy crap, I got so pumped. I felt a huge difference between a 1983-P and a 1983-D. the 1983-D was weighing more, Yet i don't have a scale. Am i exited for nothing? Do i have the realio dealio? Sorry, I don't have a camera either!
No scale , that's the only way you'll tell . But it's highly unlikely , like finding a MS-67 R , '09-S-VDB in pocket change . You could make a make shift scale or take it to your local PO . tell them you want to ship a bunch of them and need the weight .
Postal scale won't help. They weight to an accuracy of .1 OZ or 3 grams. Without an accurate weight there is no way to answer the question.
