I'm still willing to sell 2-packs (1 of each Ether and DRK)
There will be 9 available.
Will look for some smaller mailers..cheaper too.
The combined weight shouldn't add any more postage.
Since the coins are inexpensive, you should be able to get by with either an cheap envelope with cardboard / box backing inside, or better yet buy a package of 5x7 or similar padded mailers from Walmart/Target/etc. Sent by 1st class, shipping should be less than $2 a piece within the US if no tracking provided.
I'm sure the community would appreciate taking you up on the offer, since we weren't able to do a group buy.
My thinking is the shipped cost to you should be around $13.25 per coin, then whatever packaging material and shipping cost to the other people is extra. Whether sending one or two coins shouldnt change the shipping cost that much, if anything.
