This is Strathearn's regular Crown paperweight but its designation is PSFC202 Crown even though it is not faceted as are the other PSFC series weights. See the PSFC162 album for the overlay crowns. This PSFC202 Crown weight was also part of the Strathearn special "Collectors Range Limited Issues" and was also limited to 150 each per year was supplied in a Special Presentation box and was either signed and dated and numbered on the pwt or on the accompanying authentication card or both to some degree. The first one shown has a yellow and white signature and date cane S-71 and etched #5 on the base, the second one is not signed, dated or numbered that I know of, the third one is signed and dated S-73 and the fourth one is an S76. I suspect as with the other PSFC series issues that these were made from around 1970 to 1980.
