I sold a trocadero 27, the larger size for a teacher at my son's school and it went for a drop over 300 and was in near mint condition, light vachetta and immaculate inside w/ crisp canvas, the bag retails for 900 maybe? anway, on ebay that is not a popular style so that is a huge loss but many would think that's a good return for a trocadero.
You did do well with the Trocadero on eBay. I sold one similar in excellent condition for only $225. I was surprised to get that much. Although, most Troc's I've seen are in awful condition
