DTE Animation Cel - Storyboard - Hand drawn mock ups etc

I have several pieces of the original artwork, to include an original handmade animation cel and production background, story board as well as original hand drawn concept artwork all with provenance and letters of authentication from Joe Pearson as well as Epoch Ink

I recently suffered a pretty severe injury at work and am needing to raise some funds. Because as many of you may know already that workman's comp doesn't pay very well!

I really have no idea on the value of these items, and I'm not looking to just give them away either. If you are interested in anything, please DM me. If you have any ideas on value or somewhere I could research for that info I would appreciate it.
