OP I can see on another thread you have listed this item on eBay. May I suggest you ditch or opt out of the Global Shipping. No one, especially in Wales will pay $18.90 (£11.25) for this to be shipped internationally. Basic economy shipping is all that is required unless it reaches a high amount in bids.
Interesting. However, none of what you wrote about Courtney and her book conflicts with what I wrote, i.e., #1 & #2 "plus" factors and #1 & #2 "negative" factors, nor did I refer to them as trade tokens or pub tokens, just the generic "tokens". edit//daveydempsey makes an excellent point; If the token were mine, and sold for $20 or less, I would put it in a manila 2x2, tape that to an index card, then a second index card, and insert it into an ordinary envelope so that the token is positioned in the lower half of the envelope, where the cancelling machine won't bang it -- well under one ounce, and roughly $1.25 overseas-outbound from the U.S., or 70 cents domestic. Of course, I would not have put it on eBay at all, at least for the first try.
