I need a litte help with getting coins graded.

Yes shipping and return shipping is not included nor is anything beyond the standard tier, plus more $ for any speed service, variety, oversized, first strike, mint errors, etc. and some coins (generally high end/cost coins may not be suitable for the free grading certificates, some won't even fit in the category they offer, I believe you need a maximum value of $3000.00 any more you will need to use a higher priced service tier.

You must submit all 8 coins at the same time, they also must be similar in type, all us or all world.

briank - if you want it slabbed to say the mint error and what it is - then both PCGS/NGC will charge you for it. If the coin was not really a mint error - but rather how they all were... then I don't think you get charged anything for the designation.
