Belgium, Baudouin I, 1 Frank 1990, flat strike.

[Arminius]

Hello,

i found this almost faceless KM 171:



Belgium, Baudouin I, designer: Harry Elstrøm, Brussels mint, 1990 AD.,
1 Frank (18 mm / 2,75 g), Dutch text type, nickel plated steel, 2,75 g. theor. mint weight, mintage 200,060,000 , coin alignment ↑↓, plain edge,
Obv.: BOUDEWIJN I / HЄ , his head facing left, designer´s HЄ -monogram behind, flat strike at face and legend.
Rev.: 1 F / 19 - 90 / BELGIË , field divided into three parts by a three-pointed star, crown in upper left, value in upper right, BELGIË below, flanking date across, flat strike at top of 1 and GI.
KM 171 var. .

The weight is ok. So there was enough material. Maybe a die defect or technical problem during striking?

Maybe a die defect or technical problem during striking?

It does not look like a defective die, rather an overly amount of grease between the die and the planchet.

I agree. Greasy die. This seems to be a modern problem. I have seen a number of euro coins from different mints with this production error.

Impressive, Aernout. I would say "1fr 1991VL Dubbel teken.JPG" is also a greasy die.

I have in my collection this 1 Franc with extra metal on both sides.

Serious die damage, possibly also above the F. This piece should never have escaped quality control and the faulty die should have been replaced, as the damage should have been quite obvious. Not sure what could have caused it. My best guess is that the press was operated when no obverse die was mounted.

I have also 2 coins with the same defaults.

Interesting. In those two coins the damage is very similar, but not on two sides. Moreover, they have different dates. Maybe the die damage has something to do with the broad band below the country name, since it always seem to continue that band.
