What does PROOF, BE, BU mean ?

BE: Belle Epreuve or PROOF in English, coin of numismatic quality, shiny, struck with a die finished by hand and in a limited series. The result of this procedure is that there will be no defects on the coins.

BU: Brilliant uncirculated, coin of slightly lower quality than the proof coin, machine pressed, without mirror effect like the proof coin.

PI: Bullion coin, the quality is standard and their main purpose is to preserve and protect its heritage during troubled times.

Which of the parts to choose?

From our perspective, the BE gold coin has a higher trading premium. Which means that with the same metal weight it costs more. For greater liquidity our choice would be an investment type coin.
