Really difficult question to answer because there are so many different factors to consider, but the bottom line is that you are the only one who can truly decide what the price should be & if you struggle to believe in your true worth & ability then pricing is always going to be a problem for you, (ask me how I know lol)
First think is to decide on is are you running a Business or is this purely a Hobby. If it's a Business then there will be a minimum price you can charge for your items based on costs & the profit you need to make for the Business to be a success & grow. If it's a Hobby then you don't rely on it to Live & pay your bills so your pricing could be different BUT that doesn't really mean that you should be selling things cheaper just because it's a Hobby, you still have the same worth & skills regardless.
If it's a Hobby then you could just make stuff & give it away as someone else has already mentioned, asking people to donate to a charity is an idea I quite like, if you do just give stuff away you will quickly find you have a lot of new friends lol.
You could price it just on what it has cost you to make so your Hobby is basically free to you BUT if you do that then don't forget to add something for things like consumables, rags, polish/finish, sharpening stones, tool wear etc etc Oh & don't forget about electricity unless you have a foot treadle lathe & even then you need to eat to be able to power it.
You could price it the same way but add a small profit that you could put to one side so in the future you can buy new tools & equipment, treat the family to something or what ever else you fancy doing with a little extra money. Researching somewhere like etsy might work looking at the lower to middle end of what people are selling items for, where you pitch yourself within that is really down to you.
Or you could price it with a much higher profit margin more like a Business, to do that you would have to research quite a bit on what that sort of item generally sells for, if your doing that & looking at places like etsy, not on the high street etc etc then look more at the higher end of what things sell for. Also make sure your looking at like for like items, things like spalding, figure etc generally give things a higher perceived value & can also take more time & attention to make well.
Always difficult to tell just from pictures but it looks like you have done a good job on those items, biggest problem you may have is convincing yourself that your work is worth what you are asking for it. lol
