I wouldn't buy American KJV for reading or studying if I were you. Because it changes the true meaning of "ye" and "thee". Not only that but other words as well.
For example, in John 3:7 KJV:
Marvel not that I said unto
thee,
Ye must be born again. (Jesus is not talking only to Nicodemus, but includes us too)
But the American KJV shows:
Marvel not that I said to
you,
You must be born again. (This sounds like Jesus is talking to Nicodemus ONLY.)
From Websters Dictionary:
YeYE, pron. The nominative plural of the second person, of which thou is the singular.
But the two words have no radical connection. Ye is now used only in the sacred and
solemn style. In common discourse and writing, you is exclusively used.
From Strongs:
yeG5209
ὑμᾶς
humas
hoo-mas'
Accusative of G5210; you (as the object of a verb or preposition): - ye, you, (+ -ward), your (+ own).
----------------------------------------------------------------------------------------------------------------------
(no word "thee" in Websters)
theeG4671
σοί
soi
soy
Dative case of G4771; to thee: - thee, thine own, thou, thy.
I suggest that you watch this 4 min clip of David Daniels explaining about the uncommon Emglish words, such as Thou, Doeth and so on.

UPDATE: I checked to see if American KJV passes PCE test. Here is the result↓↓
1. "or Sheba" not "and Sheba" in Joshua 19:2 - failed
2. "sin" not "sins" in 2 Chronicles 33:19 - failed
3. "Spirit of God" not "spirit of God" in Job 33:4 - failed
4. "whom ye" not "whom he" in Jeremiah 34:16 - failed
5. "Spirit of God" not "spirit of God" in Ezekiel 11:24 - failed
6. "flieth" not "fleeth" in Nahum 3:16 - failed (spelt "flees")
7. "Spirit" not "spirit" in Matthew 4:1 - failed
8. "further" not "farther" in Matthew 26:39 - failed
9. "bewrayeth" not "betrayeth" in Matthew 26:73 - failed (spelt "denudes")
10. "Spirit" not "spirit" in Mark 1:12 - failed
11. "spirit" not "Spirit" in Acts 11:28 - failed
12. "spirit" not "Spirit" in 1 John 5:8 - failed
Failed all 12. Therefore the American KJV isn't PCE.
