Recently David Rago had a Charles Hall carved chest for sale on his web site, RagoArts (sorry for the poor quality of the photo). It was listed as an "18th century pine blanket chest elaborately carved by ROYCROFT artisan C. S. Hall, 1930, with a Dutch landscape of windmills and fishing boats. Some scratches to edges of top. Inscribed 'Designed & Hand-Carved at Roycroft by C. S. Hall, 1930.' 29" x 481/2" x 17"." The price asked for this piece was $15,000.00.
I am sure others pieces of Hall's carving exist and occassionally make their way to the market. If you are aware of any that are for sale please let me know so I can add them to the web site.
