I bid on the coin in good faith, trusting in the description that it was an "AE sestertius (32mm, 23.71 gm, 6h)." However, it weighs 12.87 g and measures 26.4 mm in diameter. The collector's envelope that came with the coin even called it an as. I already have an example of the dupondius in my collection (albeit at a lower grade) and I purchased this one entirely because it was described as a sestertius, which I need for my collection. As an as, the coin is not worth the price I paid thinking I was buying a sestertius. While I am willing to ship the coin back to Heritage for a full refund, I like the coin as an example of the as to compliment the dupondius I already have in my collection, and it's certainly an upgrade. I do, however, think I paid more than fair market value had the coin been properly cataloged and properly described. So, I wrote them asking for a partial refund of the purchase price (about 1/3 of the final price, counting buyer's commission and shipping). We'll see what they say about my offer. Here's the dupondius, by the way. It has different breaks in the legends on both the obverse and the reverse. I don't consider the coins duplicates, though some collectors would.
