Coral ID? Acro or Slimmer or...

Hi All,
Been out of salt water game for a while, well had a tank for the last several years, just not been active and practically forgot the names of all my corals.
Can someone give me a name and possibly value to this one? It's about 5 to 6.5 inches long and probably about 3 to 4 inches in diameter.
 
Way to test if its a slimer is pull it out of water for a min and if it slimes up like snot then its a slimer if it only kinda slimes up then acro. I have both and they look about the same. Slimer has more of a green color.
 
From the pic, it Looks like an acro to me that has lost its color through say an alkalinity issue, shipping etc. I think once you color it up you can get a better idea of what it is. Once its stable and you frag it and put on a plug. The new growth will show you the true color. I have had big colonies loose color due to alk issue's and they take a long time to recover color depending on the coral, but the frags grab new color immediately. JMO
