A couple of things...
1. Coral Collection is closed, and apparently the brand has undergone quite a change from when it was the go to place for high-end BTAs a few years ago. I wouldn't use the Coral Collection names to compare to unnamed nems. This leads me to...
2. If you don't know the lineage (and I've said this before a few times now) then you don't have something worth a lot of money. Without any sort of proof, people won't shell out big dollars for a nem without a history to it. If someone can trace the lineage back to Coral Collection or another reputable dealer, then the price is significantly higher than a nem without lineage that looks EXACTLY the same. For example, on other LFS sites, I've seen nems called CC Supernova or CC Funburst. We assume CC to mean Coral Collection so the lineage of that nem can be traced back to Coral Collection.
In the OP's case, it looks like a nice RBTA, so it may fetch a higher price than the typical RBTA, but it can't be called anything other than that. As previously said, people/ can attach names to them but they are only worth what people will pay for them.
