Colombia KM#193 or KM#274? [решено]

I have these two coins, both are 1916. What I want to confirm is my assumption that for that year:
- KM#193 was only minted in Bogota/Birmingham so ALL examples have a "B" under the crest
- KM#274 does NOT have a mintmark (thus those are my coins)

Thanks for your insight.

This is incorrect. KM#193 coins from 1912 till 1923 struck in Birmingham/Bogota don't have a B under the crest.

Thanks Essor Prof. I guess I have a KM#274 to add to my swap list now (hopefully to swap for a KM#193)

The two coins you have are indeed KM#274, not because there is no B, but because the KM#274 has larger lettering (easy to see on the DE (D and E much closer to each other than on the KM#193 coins) and best to determine: the much flatter base of the neck.
