What Happened To Graces Silver Cross ?

From the text:

An open coffin draped in bunting rested on a raised platform at the far corner of the room; in it lay the dead man, looking exactly as she had found him, except now he was dressed in the costume of Uncle Sam—including the tall hat. Between the waxy hands, folded across his chest, lay her mother’s silver cross.

Note, the cross comes up listed in the things that are missing.....

Lost: Silver cross on filigree chain, topaz pin and earrings, gold-filled cuff links. Return to Grace Windsor Wexler, 3D. REWARD!

In the end....

(Grace Wexler’s silver cross never did turn up.)
