SolvedCG76871 | Chattels: mixed collections
From HM Revenue & Customs · Capital Gains Manual
Many of the types of asset listed in CG76870 will be owned as part of a collection. By their nature such collections may include both wasting and non-wasting assets and these may be disposed of at the same time or to the same buyer. If you are dealing with this type of case, you need to obtain as full and comprehensive a description of what has been sold as possible. Where the assets have been sold at an auction, you will need to obtain a copy of any catalogue or brochure.
Where a collection of assets has been disposed of at the same time, the consideration should be apportioned on a just and reasonable basis, TCGA92/S52(4).
