<p>[QUOTE=&quot;krispy, post: 622546, member: 19065&quot;]<b>IF </b>those coins are/were real and not fakes embedded in there, I feel that the acrylic-resin casting process itself would have done the damage to the coins and that extracting them will reveal what is not presently visible through the cast acrylic. That is, no matter what method you go by to remove them, once separated from the bulk of the acrylic you will be left with coins that have bonded residue to them. Any chemical treatment to remove this will further effect the surface patina / toning that the coins may have had prior to encasement. <b></b></p><p><b><br /></b></p><p><b>ALSO,</b> beware of using chemicals to melt other resins, polymers and plastics... they give off serious noxious and toxic odors which are repiratory irritants. If you go this route, do it outside, away from your home/property for safety and know how to properly extinguish fires caused by chemicals. <b>Wear a proper graded respirator for working with any chemical solvents.</b> With that said, it might be easier to just crack the acrylic with force and see what you can do <u>without chemicals</u>. </p><p><br /></p><p>Did they actually make acrylic coin embedded toilet seats in 1949? since you mentioned it being like 60 years old... Thought these were more modern kitschy home gag decor. Lucite and PlexiGlas were invented by DuPont in the early 1930s so I suppose it could be that old. At any rate, I did some further Googling and found a thread about <b>Extracting embedded coins from Lucite</b>, read on, it may help: </p><p><a href="http://www.coinbooks.org/esylum_v09n04a22.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.coinbooks.org/esylum_v09n04a22.html" rel="nofollow">http://www.coinbooks.org/esylum_v09n04a22.html</a></p><p><br /></p><p>Please note that the above link stresses the flammable nature of solvents and the necessity for ventilation when using these materials.[/QUOTE]</p><p><br /></p>
