High Speed Train #4511 worth

Based on the items listed on your screen, the catalog data I can access does not have specific, detailed pricing information for "High Speed Train #4511" or "LEGO High Speed Train (4511-1) (World City)" to give a precise valuation. The first item is listed with a used value of $360, but I cannot pull further details on that specific listing. For the second item, no price was provided in the catalog data. To get a more accurate picture of what these sets are currently selling for, I recommend looking at the live eBay listings shown on your screen to compare the asking prices against the $360 used value for the first set.
