The legend of the sand dollar:
The sand dollar, no intrinsic value has he
Only reminders of our Lord, up from the sea
Four little holes for the nails which held him to die
Another hole too, where the spear pierced his side
A star for the manger, a bell to ring
And inside five doves, his praises to sing.
Interesting how you can find symbolism wherever you look - if you look hard enough. Thanks Mom!
