[Mr. Creosote]

If this topic has come up before, please let me know. A hypothetical situation: You're looking through Ebay's completed listings and notice that a $5 Dunes chip sold for $45.00. You think, "I've seen that chip somewhere..." You get the cigar box from your closet and, lo and behold, you have 130 of these same chips. You are not well off and bills need to be paid. Ebay looks to be your best bet. Do you list the $5 Dunes one at a time, and continue to list each subsequent one?
It seems to me that bidders will quickly lose patience with this, never knowing when the supply will run out. (or worse, think that you're knocking them out on your "Mattel Easy-make Chip Maker") Do you list the chips as a lot of 130, or in similar small lots? Should the bidders know how many you have? Do you list on CT? Maybe you don't have enough "chips" to list. Is there an ethical element to not disclosing the number you have? What would you do?
