Ultimately, club lambs are only worth what someone is willing to pay for them. Price is depended on quality, genetics, breeder reputation and market. Also keep in mind what sale barn prices are. Any 60# lamb is going to bring $130 at the sale barn. You are putting a lot more money and time into your show lambs, between genetics, show feed, shearing, having the buyers out to your farm, support after the sale, etc. That all has a dollar value.
Looking at the quality of your lambs, your prices seem on target, if not a little low. Your Black Velvet buck doesn't impress me but Dangerous Games looks like a move in the right direction for you. As far as pricing them... You just have to base it on demand. If some buyers are shying away, I wouldn't be concerned so long as you have others who are willing to pay what you're asking. If you don't have other buyers, then you have a decision to make. Honestly, it very well may be better for you to take those bottom end lambs to the sale rather than showing them as show lambs. For one, it's less head ache. Load up the trailer and drop them off and you're done with it. No scheduling with buyers to come out, no after the sale support. And even more importantly, your reputation is riding on every lamb you sell. Those bottom end lambs can hurt your reputation as a breeder. Every breeder has at least a few no good lambs each year. The smart ones don't try to sell those as show lambs. I have one in my pen right now. Full sibling to my best lamb last year but he's no good. I had someone call looking for an early, cheap lamb but I opted not to sell him. I don't want my name attached to a last place lamb.
And one more thought... For us, the online sales have really helped us tremendously. The local kids here won't pay more than $200-$400 for a show lamb and only a few will go to that upper end. I can't pay my feed bill selling lambs for less than $300. The online sales, being an auction format, really have helped me determine what my lambs are worth. If they are consistently averaging $600 in the online sales, then I can feel pretty confident that that's what they are truly worth based on quality. But I'll never get that for them selling them locally. So the second thing the online sales have done is expanded my market. I no longer have to rely on those buyers that will only pay $200. I have sent lambs into eight or nine different states in the last three years. I sell more lambs to other areas of the state than I sell locally. So that may be something to consider too.
