After more than a week, I was alarmed enough at how long it was taking to appear as a submission on their website that I nearly emailed them to inquire as to its whereabouts, but decided to wait. The coin finally appeared on the website the next day, so I felt much better at that point. Then, it expectedly took another several days to enter grading, followed by verification. I decided to check my grade today at lunchtime, and when I did, the submission tracking page hung for over 10 minutes before I gave up on it. Tonight I checked again, and this time there is no record of my coin, or even of my submission. I've since emailed them, asking what is going on? Perhaps they're experiencing difficulties with their website, issues with their database, or maybe they've lost my submission? I suppose I shouldn't worry over nothing, at least not until I know that it's not really nothing . . .
