Not all coins come with COA or with Box (in case the mint doesn't make it).
If available or not, it is clearly specified in the specifications and if box is available is usually shown in pictures too. With Box we mean also a presentation card, a folder, a frame etc. It simply means that coin doesn't come only in air tight capsule.
We strive to help in case something goes wrong. We will do our best to locate a delayed or missing parcel and in case after a reasonable time we are not able to locate it, we will re-ship your items at no cost for you, no questions asked.
