@Billie: I hope it all works out for you, but something doesn't sound quite right. Per the Airtites web site, the A16 holder for 1/10th-ounce gold coins and the A19 for small cents have the same interior depth - 0.062" (1.57mm). They are, after all, both "A" model holders.
If the vendor sent you A16 holders by mistake, the cents would not have fit in the smaller diameter holder, but your image shows a cent properly seated in the holder but with a depth issue vs. a diameter issue.
Of course, I could be misinterpreting things, so I look forward to your follow-up report after the new holders arrive.
