For the collector, this ia a used Armetale Pewter Child's ABC Plate manufactured at the Wilton Armetale Company.  

Wilton Armetale Company is a family-owned and family-run business founded in 1892 by Ralph P. Wilton, Sr. in Lancaster County, Pennsylvania. Wilton Armetale® products are still individually cast and meticulously hand-finished so no two pieces are exactly alike. Wilton Armetale® products are sold in department stores and specialty stores throughout the United States and internationally.

Armetale® metal is a unique, non-toxic aluminum-based alloy, making it ideal for cooking and entertaining.   Each ARMETALE® product is a solid piece of metal with no coating applied.  It comes in two finishes – one finish is a high polish similar to silver and the other is a matte finish similar to pewter.
