Center Industries Date Stamped magazines Question

[Franchise]

I have a chance to purchase CI pre ban mags, but i have a question about them. They are both stamped, but the stamps are not alike. One is a deep/heavy stamp and the other is a light stamp. Is this normal?

Normal. Some have no stamps, etc.

thanks. being new to this and in an AWB state makes me question the smallest detail.
