From a financial stanpoint the 1890 isn't worth submitting. Its FMV is what like 50 bucks? Its like 15 a coin (probably 20-30 since its not a modern) plus shipping both ways which means youd be spending a substantial amount of the value to have it graded.
If you want it graded go for it, but unless you got the morgan for face value you wont be making any money by doing so
