the oddest part of this coin IMO is the running wavy line along the bridge start to finish but does not appear anywhere else. everywhere else arrows are other than bridge have noticeably weakened features or are gone. you really see it in between the sails in I believe the 5th picture. the bridge section on the right does not touch sail. features in the water are missing. also... if this makes any sense. if you look at a quarter in hand the sails are raised right? these are all flat??
The squiggly line in the bridge is a normal feature of that coin. Looks like you have a regular quarter.
The wavy line you see is a representation of the trusses under the bridge. Normal for the coin. Everything else is die deterioration and 17 years of circulation.
ya know... I looked at 2 other quarters for comparison and those wavy lines are not visible. hence my excitement lol. could die deterioration cause all the features in between the main sail and the smaller sail to vanish completely??
could always look online at pictures for uncirculated or proof coins to see design characteristics instead of other circulated change.
