I thought I would just share with you on how I try to figure out if a coin is exhibiting a possible MAD Clash.
Below is the MDC-1c-2000-02 and is also illustrated on the MAD Clashes web site.
When we just look at the top photo by itself, sometimes it can be difficult to try and figure out what letters may be involved with the clash.
First, we have to understand that the clash remnants on the coin are going to be inverted and flip-flopped (mirror image). Also, the lettering will be incuse and the surrounding field around the lettering will be raised on the coin. To put it another way, it's similar to a negative from film. With a negative for film what is black is now white and what was white is now black. However, with the coin, the associated lettering involved with the clash is now incuse instead of raised like we normally see on a coin.
To help me visualize, I do an overlay. What I simply do is my first photo is of the suspected area and I note the magnification that I take the shot. Then my next photo is of the suspected area on the reverse of the coin that I believe is probably associated with the clash seen on the obverse. Again, this second photo of the reverse is at the exact same magnification.
Now, I just simply flip-flop and invert the second photo and make it a transparency.
Then I move that transparency photo over and position onto the first photo. Now it's just a matter of moving the transparency into position that matches to all the lettering. The end result is the bottom photo with the overlay transparency from the reverse superimposed over the MAD Clash remnants.
With the second photo, we can now easily visualize the lettering involved with this particular MDC-1c-2000-02 MAD Clash listing.
You can do this on any type of clash and you can experiment. Have fun and make technology work for you.
