In most retail stores I have seen Maricultured Acros like the first one can go for anywhere from $50 to $120. Yours seems to have some great color so I would pay around $100 for it.
The Soft Leathers do not contain as much value unless they are some rare color, basically anything except that pink-tan fleshy color. So yours, if it is a common species of Sinularia, could go for about $40-$50.
That's my 2 cents on value, which can be a very opinionated topic, and can vary quiet a bit city to city, country to country.
