The book-currency feature was created 6 years ago as part of an ambitious project that never got finished. It added several hundred unused lines to the options code so I removed it as part of rewriting that options code in C++. I thought that it wouldn't have gotten set in any books.

I've restored the feature to 5.1 so you and anyone else with the feature set will be able to upgrade.
