It does show that the holes were punched after the coins were struck. Ex. Spink from Auction 14007 17-18 December 2014, Lot 139, where it was in a group lot with two other copper coins, described as: "Centime, 1888, same type (cf Dupriez 69 ; KM.1), lustre, deposit on legend at one o'clock, double holed, uncirculated". Likely conserved by PCGS.
