This whole grading thing was hard for me to comprehend. But basically, like basebal says, the coin needs to be worth enough to get graded. I can not grade coins at this point. But sometimes a dealer will take a gamble that some coins are 70's, thus offsetting their cost of grading. That was the point of a topic similiar to yours, where I was buying graded business strike
ATB Quarters. Majority MS66, rare MS67. It's the 67's that justify the expense (they hope).
That whole PCGS submission form is a little complicated. Basically $8 for handling, doesn't matter if you have one coin or ten, right upfront. I believe modern coins are the cheapest category (1965-present) like $15. For those big 5oz
ATB's, oversize holder = $20. First strike + $18. So if you are looking at grading a 5oz
ATB = $8 + $20 + $18 (if you want FS) = $46.
Dont forget to enclose return shipping costs!!. I submitted 2 valued at $200 each (because you need insurance), think return shipping waws like $35. BTW, add in your cost to ship it to PCGS!!! They suggest registered. My post office said like $35 but PCGS is in CA and I'm in PA.
My total cost 2 5oz
ATB's is like $138. $70 per coin. Paid the mint $179 + $5 shipping = $184 + $70 = $254. If I sell it, I would need $254 to break even. Maybe there is a SP-70? Idk.
Dealers get a break from the thread I learned, think they need to have 60% of coin submissions >100 coins of like (in the small
ATB business strike) at MS66 or something. I forget.
BTW, I joined to get $199 + 8 free gradings, It works out for me since I have platinum and gold which would normally cost $32 vs $15 modern (>1965) fee.
Confused? I sure was. Hope this helps.
