Here are 3 links from the same seller price range from ARS 1000 to ARS 2500 (about USD 64 to USD 162)

No COA, the seller says that he is friend with the bellboy of the Four Seasons Hotel where she use to stay in Argentina.

This one contains two singaures on the front and the back of the cover (price ARS 1000 , around USD 65)

The second one cointains only one signature on the front cover (price ARS 1500, around USD 100). I think its weird that containing only one signature is mid price more expensive that the first one at ARS 1000

The third CD single cointains three singatures: front cover, back cover, and the cd signed. On the front cover is dedicated with "All my love" (price ARS 2500, around USD 162)

Any thoughts? Are they real? Should I buy them? Trying to decide between the first or third cd
