Esperanza Rising What do Tio Luis and Tio Marco deliver to Mama?

I believe this refers to the belt buckle belonging to Esperanza's father. Tio Luis brings the buckle to Mama just before Alfonso and Miguel deliver Papa's dead body.

I think they brought mama a marriage contract for tio Marco to marry mama because it says that they tio Marco wannaed to marry mama but she refused cause her husband died and she doesn’t wanna upset papa Esperanza and the family.
