I have given up shopping ebay, but use as info source and value trends. Yesterday a very good well presented mc gold heavy case one with common 15j Elgin went for a high $5800. That is interesting to me since I have several. About $2000. gold value. I recently got similar from a fine and experienced dealer for $3000 with a better Elgin movement. Same unused condition. There were 40 bids and 23 bidders. Until the last 16 seconds it was under $4000 a good high price. 3 final bidders in 13 to 16 seconds were $4800, $5600, $5800. Ebay auctions can be good for sellers and this one had no return provision. Photo of it, vertical. Mine, horizontal. The auction one is a little heavier but not as colorful with the big old style stem and maybe a little better quality case work. About same age.
