What is the value of an 1879 rev 79 US Silver Dollar?

AnswerThe value of an 1879 Morgan dollar depends very much on its condition and mint mark. Check above the DO in DOLLAR on the back to see if there's a mint mark letter.

Numismedia lists the following approximate retail values as of 01/2010:

No mint mark:

Very worn condition - $17

Moderately worn - $19

Slightly worn - $21

Almost no wear - $23

Uncirculated - $34-3,000 depending on quality

"S" mint mark:

Very worn condition - $17

Moderately worn - $19

Slightly worn - $20

Almost no wear - $22

Uncirculated - $35-2,000

Note there is a variety of 1879-S with the reverse design from an 1878 coin; this is worth somewhat more.

"O" mint mark:

Very worn condition - $17

Moderately worn - $19

Slightly worn - $20

Almost no wear - $22

Uncirculated - $70-15,000

"CC" mint mark (beware of fakes):

Moderately worn - $200

Slightly worn - $350
