The proposal for Cardano NFT royalties CIP-0027 suggests that a nameless token should be used to store the royalties information.

Usually a mint transaction looks something like this:

cardano-cli transaction build-raw \
--mary-era \
--fee 195509 \
--tx-in b1ddb0347fed2aecc7f00caabaaf2634f8e2d17541f6237bbed78e2092e1c414#0 \
--tx-out $(cat payment.addr)+4804491+"1 677d3bbe3e01eeab498cd8786f7d261d92bd6ecea12109a332e86374.MountainGorilla"\
--mint="1 677d3bbe3e01eeab498cd8786f7d261d92bd6ecea12109a332e86374.MountainGorilla"\
--out-file matx.raw

As we can see in the mint part, the new token is a combination of the policy id 677d... and the token name MountainGorilla.

Is there any example how a nameless token can be minted?

Native assets as far as I’m aware can have the empty string for the token name. In theory you should be able to just leave the token name empty so the token ID will just be the policy ID. I’m not sure if the . is still required though, but as you can see from the docs, it’s just a ByteString object, which can be empty.
