@Onetallgentleman,
I’m not a moderator, so this is just a guess.
Your posts contained hypertext. Now I know that they were just pictures of your artworks, but they could easily be seen as spam, especially if you’re a new poster.
Instead of posting hypertext post the image instead, you should be OK.
Having said that you’re not likely to find a satisfactory answer. People who deal in Art are very jealous of their knowledge. There are websites where you can pay a fee to access the prices that various art pieces have gone for over the last few years.
And that’s the only way you’re likely to find out, and it’s not cheap. The costs are prohibitive that unless you’re in the business there’s no point paying.
The cheapest I’ve seen was about £1000.
Unless you think your paintings are worth more than that there’s no point.
Sorry to be the bearer of bad news, but I’ve had problems valuing some of my pieces.
You’re best bet would be to make friends with the owner of a local art gallery and pick their brains.
