Advice On Selling in the Current CV19 Climate

We have a number of Lego sets including Duplo such as the various Thomas The Tank sets and we're looking to sell these but in the current CV19 climate we're not sure if the normal means (i.e. using Lego specific websites ) or if we're better off garage selling these. The items we're trying to sell like the Thomas The Train do not have the boxes or instructions but they are complete and the bricks are in very good condition and we are a smoker free household; these bricks have never known smoke. Attached is an image I took of one of the containers that we have the Thomas The Tank Train sets in while we're organizing the Lego/Play room. We are re-organizing the Legos/Duplos and so the Thomas sets are in various plastic containers currently. 

So what are you guys thoughts/recommendations on selling Lego sets that have no boxes or instructions but are in great condition?
