2020 Mexican Silver Libertad 5-coin Proof Set in Wooden Banco De Mexico Presentation Box. Proof Libertad 1oz and fractional coins have very low mintages for 2020. This Libertad Proof Set is a keeper, certainly one to have in your collection! The set does not include a COA, since (to my knowledge) Banco De Mexico did not release a proof set in this 5-coin format for 2020.The 2020 proof coins were obtained individually; the genuine Banco De Mexico wooden presentation box included in this sale is from a prior year proof set. Thank you for your time, and have a great day! The item "2020 Mexico 5-coin Libertad Silver Proof Set in Display Box Rare, Low Mintage" is in sale since Sunday, April 18, 2021.
