Newbie Needs ID Help! Pic included

Hello all and thanks for anyone that can provide help. I’ve searched up and down and can’t ID this mark.

The mark is on the bottom of a small, pierced edge, sterling marked basket. the numbers 1177-4 are also stamped on the bottom.

I don’t know if the first part is the letter i in a c or a pick axe in a c. The A in the odd shaped shield in beyond my knowledge of silver and looks like a sun in a circle.

Thanks in advance for any help!!!
