I pulled up your ad out of curiosity and immediately didn’t even want to read it because there really isn’t any info about the collection or pics of it. I have been selling on eBay forever and getting the possible buyers attention is what I have found to be the most important thing when selling online. Make it stand out from all the others because the more views the better your odds will be in trying to sell things. I may be interested but I have no idea what you are selling and that is the problem. Good Luck and I hope it works out.
PS: You might have more luck selling on Mercari. Just a suggestion
