I'd seen an 8-letter version of 17d and didn't consider an enumeration error. But I'm not particular about cluing details. I thought the first letter was a sporting abbrev. rather than currency.
With six in after an hour, and one of those I can't parse, I cheated 1ac to get me started. However as I can't see either a definition or a parsing in that, I gave up. Three prize DNFs in a row!
