Rookie needing advice
Full disclosure..... I am a baseball card guy with no expierence with currency but the old bills fascinate me. I am wanting to put together a run of all denominations of a particular year when they were all available from a $1 through a $1,000 bill.
I want to buy these graded for security and investment. So can I get some tips on what year makes most sense to go after when all are available and second what grade. I am used to the baseball card world of psa 7 or 8. So what currency grade is equivalent to that? Is there more than 1 grading company? Most recommended? Thx
