I'm not familiar with die clashes but I am interested in learning. Recently I found this 1890 Indian Head Cent and I think it has a die clash. Viewing the coins reverse it seems to me there is an impression that looks like the gaps between the feathers of the headdress on the obverse. There is also some odd doubling with the lettering. I googled die clashes but didn't find much. If anyone if familiar with a group or webpage I'm all ears. Comments are welcome.
Thanks to your photo over-lay and an H.E. Harris 16x loupe I can now make out the reverse inside wreath line superimposed onto the obverse on the face of the bust.
1890 variety # 5 misplaced date in denticles or # 8 rpd. As your images are not clear enough to determine between the two varieties. I lean towards the #8 but do see traces of the 89 in the denticles. http://www.indiancentvarieties.com/1890_variety005.html http://www.indiancentvarieties.com/1890_variety008.html Clash marks as well as die cracks can and cannot be used 100% as markers! Clashes and die cracks may or may not be present to determine the variety or vam. As they used to determine die state. How many or long the die been operational, and it clashed durring a strike or cracked from heavy useage. I have seen this particular variety before and it may have the 8 and 9 in the denticles, hard to determine from your image. I will tell you this you contact David from this web site and he will do an in hand attribution of the specimen. He does it free of charge just required postage to and return. If your specimen is better than the known variety he will ask to make it a "plate coin" I have several from discovery items, and better grade varities. https://www.indianvarieties.com/ another good reference for IHC. Just beware of dis and misinformation that is all to offten posted by inexperienced members.....I hope this gives you a better understanding of your specimen.
