Definitely a nice piece. Legs are on ebay for maybe $20 so that will not really impact the price you sell it for. You will likely get in the $250+ range as other posters pointed out. The cleaner it is with few blemishes the higher the price obviously. There is a large and growing market for the Super Mahogany drums. This is a Super Mahogany Superstar.
The badge on your drum is the one used prior to 84. It has the 90 degree "T" in front of the word "Tama". After 84/85 they started using the slanted "T" in front of the Tama in the badge. Its hard to tell with the numbers to date it. There are some serial numbers that have the 82-xxxx or 83-xxxx or 84-xxxx and everyone assumes it means the year which it probably does to some extent but I have never seen a 81-xxx or 85-xxx. Its not earlier than 1979 as I think they were still making the satin Mahogany color or dark walnut. If you describe it as early 80's you'll be correct. The buyers who will want this know what it is. Just describe all the scratches, thats what everyone wants to know.
Also the drum is made of 6 plys of birch, 9 mm thick shell. Everyone who will want this drum knows this but its nice to put in the auction anyway.
The biggest pain in the arse is shipping it. Its large and you get hit with the extra shipping because of its size so make sure you get a maximum shipping cost to the furthest distance you are willing to send it before you list it.
Best of luck,
