Topps will say T.C.G and O-Pee-Chee will say O.P.C on the back of the card at the bottom near the copyright. I believe that's the only way to tell the difference.

OPC DA will access the real time value from control system. OPC HDA will access the real time value of historian processed. Hence the historian will save the value in their database as well as it feed to OPC server also.
Ordinary Portland Cement, also known as OPC, is a type I cement that does not only harden, but also becomes water-resistant once it cures. Pozzolanic Portland Cement, or PPC, is a type IV cement that includes a mixture of a pozzuolanic material, which can increase the strength of the concrete and reduce the amount of OPC used.
It's worth a few dollars, if someone wants to pay it. Because no Racers cards of Gretzky were produced in the 1970s. There's a "National Sports Card" card that was mass-produced in the early 1990s, and some crooked dealers tried to sell it as a "1978 rookie." It's not. Gretzky's best cards are the 1979-80 Topps and OPC cards (OPC is valued higher), as well as an oversized 1979 Sportscaster card that's pretty sweet.
Psc is always first choice because psc cement gives more strength than opc and also psc cement setting time is slower not that much it will give same strength in 28 days... Because of slower setting cracks will not appear or there is very less chance to appear cracks and it will requires lesser curing than opc..

OPC stands for oligomeric proanthocyanidins, which are antioxidants found in grape seeds. These compounds have been studied for their potential health benefits, including supporting heart health and reducing inflammation. So, next time you're munching on grapes, don't spit out those seeds - they might just be good for you!
43 grade OPC Cement it denotes the compressive strength of concrete in 43 Mega pascals will attain in 28 days. it is normally used for pavements, Non RCC structures and which are not important for initial strength. where as 53 Grade OPC Cement it denotes the compressive strength of 53 Mega Pascals will attain in concrete with the 28days, and it is used for RCC strengths and which are important to gain initial strength.
o pee chee made the first one and nooo way. the o pee chee is worth about 200 dollars
OPC-3, or Oligomeric Proanthocyanidin Complex, is a dietary supplement that typically contains a combination of bioflavonoids extracted from grape seed, pine bark, and red wine extracts. These bioflavonoids are rich in antioxidants and are believed to help support cardiovascular health, promote healthy circulation, and protect cells from free radical damage. OPC-3 may also include other ingredients such as bilberry extract, citrus bioflavonoids, and other beneficial nutrients to enhance its overall health benefits.
I haven't seen any link between the ingestion of OPC's and allergy relief. I'd stick with an anti-histamine to resolve your allergy symptoms - and see a specialist to get rid of your allergies all together.
