Add the following to “Private Collections”

There is also a collection known as the Collector’s Vault, which is also a list of art Titles and their Prices

When a piece of art Appreciates, its price is increased by 5% (rounded down)

Each Broker also has an amount of Cash, which is tracked publicly, and is a positive integer and defaults to $5000 (Cash may be written with a $ before it).

Add the a subrule to “Submissions” called “Sale Submissions” as follows

A broker may make a Sale Submission, which consists of a title of a piece of art in their collection and a clear indication the Broker would like to sell that piece of art to the collector. The same Broker may make multiple sale submissions during a single round. Sale Submissions may be modified to indicate the Broker no longer wishes to sell that piece at which point it no longer becomes a sale submission.

In the “Round Summary” after “Determine a word or phrase to be the round’s Theme and declare what the new theme is in the Round Post” add the following steps:

* For each valid sale submissions, if the corresponding piece of art appears in the collection of the Broker who made the bid, move it from that Broker’s collection to the Collector’s Vault (at the end of the list) and then increase the Broker’s Cash by the piece of art’s Price.
* Appreciate the art in all collections
