Le Creuset Cast Iron Round Wide Dutch Oven, 6.75 qt, Cerise Used Once

I have owned this for years. It was given to me as a gift from my mother. I was also given an oval Dutch oven at the same time and I use it somewhat regularly for pot roast but not this one. I thought for sure that this one had never been used but there are faint marks inside that make me think it has been used but if so I think it has only been once. I tried to capture this with my camera.
