My GCSE and A Level certificates. There's no way I could afford to pay to get copies, as they were with random boards and the cost is prohibitive when you don't know exactly what ones they were taken with, so have to pay all boards on the offchance (my school closed and they only had to hold records until I was 25 anyhow, so I can't get any information about them either).
A mint copy of Dark Side of the Moon, complete with the stickers. He hated Floyd.
My childhood toy, a raggedy brown furry rabbit puppet called Fivver.
Every photo that had been taken of me, DD and a framed one of my grandparents - the only one in existence - along with DD's first clothes and shoes. He sold those.
A musical jewellery box by Granddad had given me for my 19th birthday (I didn't get birthday presents as my mother didn't believe in them, so it was extra special) that also contained a cheap little gold 18 key pendant my sister had given me.
All of my tools in a toolbox, including the perfect set square that I had made in metalwork aged 13 and was as good as any you could buy. He doesn't do DIY, never has, never will.
And yet he still wailed about my taking everything he had because I kept my flat, albeit with the fridge, cooker, sofa, chest of drawers, carpet and the fucking bed removed when I was out, seeking legal advice about keeping him out/changing the locks because I'd woken up the previous night to him dismantling the bed from underneath me.
They all paled into insignificance compared to the one other thing he took and refused to give back for five years, though. Our daughter.
