Do you think this 1972 DDO is worth grading? https://www.cointalk.com/threads/this-is-the-second-of-three-1972-ddos.359004/
Only once! There are three different threads, each a different coin. Notice the different thread titles.
Why is this thread just a link to the other thread? Where is the third coin? This is feeling a lot like a scavenger hunt....
I say send them all into the top grader. Put your money up front as a learning experience. Some could use the money to buy a book and spend countless hours reading and studying. Or just spend money get the TPG results then wonder why .. then maybe afterwards spend money on those books ....
