If you want to print a label through eBay, select print label from your sold orders, you'll be shown a list of available services - you pick from that list. The coins you sold were listed as first class, so select first class package under usps.
A first class package has to be at least 3/4" thick, so use some bubble wrap or packing peanuts or other packing material to make your package thick enough.
