It is believed that Jay-Z’s Magna Carta Holy Grail is already certified Platinum by the RIAA, due to the new rule recently put into play stating that digital sales no longer have a 30 day waiting period to earn a certificate.

Although already certified Platinum by the RIAA, Billboard and Soundscan do not follow the same regulations as the RIAA, so we have the first week sales projection for the sales of physical and digital copies of the album that officially hit stores today (July 9th).

According to Billboard, industry sources are implying that Magna Carta Holy Grail should sell between 350k – 400k copies in its first sales week; the week that ends on Sunday, July 14th.

The sales projection of MCHG is partially based on how well the LP is performing with pre-orders, along with other factors, through digital retailers as it was made available to pre-order via iTunes on July 4th.

If Hov’s sales projection holds true, it would mark the 13th number 1 album for the Brooklyn Hip Hop mogul, which is more # 1′s than every solo act in history and only second to the Beatles who have earned 19 number 1 albums.

Keep it locked to DS for the official first week sales numbers when they are revealed next week.

Update: Jay-Z’s MCHG first week sales projection gets a major adjustment.

When the first week sales projection, of 350k – 400k sales, for Jay-Z’s Magna Carta Holy Grail came in yesterday, they were based off of iTunes pre-orders, and other factors that were unknown, but it turns out that the estimate for Hov’s opening week sales of the official retail release of physical and digital copies will be much more that initially reported.

According to Hits Daily Double, Jay-Z is expected to move between 475k-525k copies of his latest album in his opening sales week, which ends Sunday, July 14th.

With Jay expecting to do big numbers in his opening week, he will earn his 13th no. 1 album, which is the most for any solo act, and only second to the Beatles 19 chart toppers.
