Does anyone offer a service to exchange BTC for freshly mined coins?
Thanks
What do you want to do with them? it reminds me of near new years in my country where elders and parents going to bank to get unfolded money bills to gift children and each other on the new year's eve.
Directly contacting pools via their support tickets should be of any help, and also they become second handed after sending out from the address which was used to mine them. another option would be for you to pay miners so they can set your address(s) in that way coins directly is transferred to your address without having any inputs.
