Question in chargeable disposal of chattels.

This is the question that I found on the ACCA Study Hub: Louise bought an antique table for £2,500 in May 1998. In September 2022 she sold it for £6,500 (before deducting selling costs of £100). Required: (a) Calculate the chargeable gain arising in the tax year 2022–23. (b) Calculate the chargeable gain arising in the tax year 2022–23 if gross sale proceeds were £11,500. My doubt is, how do I know if the antique table is a wasting chattel or a non-wasting chattel? If it is a wasting chattel (which it isn't in the answer), it is exempt from CGT. Whether below £6000 or above, all wasting chattels, are exempt (except for p&m with CA). If the table is a non-wasting chattel, then the rules of 6000 limit apply. So how do I know?
