What Exactly Is "An Error"?

if only I could have some luck like that nice coin.

The title of an ebay listing is not a description of the item (there is a large space provided for that). The title is a series of words that gives a good idea of what the item is while putting in enough key words that people searching will find that particular item.

Another parallel example is using the term "wheat penny." True, they are cents not pennies but people search for pennies far more than cents, so not putting penny in the title would be costing you potential buyers.

But there is a line where someone is purposefully misleading in the title. For example, using the phrase "key date" for every cent no matter the date on the end of a "shotgun" roll for sale.

So while errors and varieties are different things, to most folks and as noted ebay itself, there are just errors. Thus my opinion is that you should put a variety coin in the category "errors," and use the word "error" in the title if you wish, while keeping the description as accurate as possible to the item at hand.
