Agreed.
While there was a print run of at least 10,000, this item has held both value and interest - https://recalledcomics.com/Superman75Platinum.php#:~:text=The Platinum editions are not,%24600 (circa Summer 2014).
Signed copies come with a much higher value - https://www.ebay.com.au/itm/175702404265?hash=item28e8adeca9:g:OEcAAOSwvoBkSBIx&amdata=enc%3AAQAIAAAA0Izchm%2F6842b%2BK9ujLUU%2BkV08IqH8UP4TObJToaxNyT0XHmTBsT2y7OnHe1rQucIHLCQxSA1%2B3xbvdpTyo8OHAe6lBy6wnfSxkE4%2FRNxmOf8fV2n4ShL3FkC7P8JXAAdwgpMl1U%2B%2B390exEb0hnpyIZo3CHx7gACn4cgCnSarEZBoOJJt0mjEV%2FqvG432Bp%2BcTxSTOKQIMQtcKhKCtPVLuMU3UR79Qk0DYSAq%2BQsh5gjVY1H5rrJF5sBlCxkLgZkAJCDOznMMLMMW7crMb6%2BmaA%3D|tkp%3ABk9SR_KRlbuoYg
If you have the $$$ and can wait, you can't go wrong with a signed 9.8.
