///////////////////////// Sir., sorry for late respond-------------- Generally, land is not moving , people das. Searching area, was trade post ( and ""truck stop") since 1840 to 1860, part of it became public park in 1873 w/ swimming pool. In 1986 one MD from Milwauke found ""pillar"" dollar there witch chinese marks on it , his friends dug out two sited 1/2 ( dont remember date ) //////////// Mexican reales, spain, french, and other S.A coins were legal tender in new US territory til 1850 ( in Main land )-- East coast ------ 10-20 years longer in Middle west/// My guess pistaren was lost around 1840/60. //// Actually Im observing Jllini findings ( reported or known ) for 4 years . , We have average aprox. 10-15 reales each season( last s. oldest was 1696) ( mostly smal denominations. , biggest was 2 real ) , 2- 4 french, dated 1830-50 , last season 6 cent of Hayti from 1801 . We not have coins from US mint dated before 1830( they were still in Main Land ) , except one I notice last s. , found by Kimsdad , beauty 1/2 disme from 1829 ? Most oldest coins starts from 1843 for LC, and 1851 for seatets( US mint ) mixed with foregin silvers ( mostly mex. CarolusIII ) . In today forum there were more celtic gold posted, than spain pistarens, and that was only reason I posted it here./// Thanks all for commentsTheakiki said:That's amazing. I'm not too many minutes from Chi Town. I have to wonder how it got there.
Passing through Ft. Dearborn, perhaps?
