Hello I buy and sell collections of action figures to fund my own collection, and was wondering what the rules are if I buy a collection and sell half of it? For example, if I buy a collection for £100 Sell half of it for £90, and keep the rest This would be a £10 loss, although i've kept multiple items that i don't plan on selling Would this still be recorded as a loss, or would i need to record the value of the rest of the items? Thanks
