Selling Personal items through my LLC, taxable???

I have a LLC that I buy inventory for and re-sell (mostly on eBay, about $1,000 a week). I inherited some toy trains about 10 years ago (my cost basis is @ inheritance I assume) that I want to start selling thru my LLC on eBay (since this account is a well established trusted userID).  Ebay of course sends a 1099-k each year making these toy train subject to state and federal taxes which I want to avoid. So is the process that I sell the collection to the LLC (at it's inherited cost basis) with a check made payable to myself? Would a toy train collection even be considered as a collectible by the IRS since it is not listed specifically in their publications? The collection has not really appreciated in the 10 years since I inherited it, so no tax would be due anyhow. It's just a matter of logging in a (legitimate) cost (of goods sold) for the collection to deduct off the 1099 eBay sends each year.
