The type 3's don't bring much. I have a type 2 that I had slabbed - that's the one to get! The first coin eventually got spent.
It really doesn't take much patience. I myself search coins every day. Just sitting in my chair with a loupe watching TV, one coin at a time. They jump out at you when seen under a loupe!
The DDO-003 is the third type found, hence type 3. IT cost $45 to get it slabbed by PCGS.
Did you have to pay extra to get the designation on the slab? I had a couple coins I found as errors, I thought about getting them slabbed.
